Jones Mountain Twin vs Mountain Twin Pro: Which Board to Buy?

Few snowboards carry the legendary status of the Jones Mountain Twin lineup. Designed for riders who treat the entire resort like a freestyle playground, these directional twins seamlessly blend park agility, high-speed carving, and freeride float.

However, riders choosing between the Jones Mountain Twin and the Jones Mountain Twin Pro (formerly known as the Ultra Mountain Twin) face a distinct fork in the road. While both boards share identical shapes, camber profiles, and 3D base bevels, their internal constructions deliver radically different riding experiences.

In this comprehensive review, we break down the materials, flex patterns, speed capabilities, and real-world performance of both models to help you decide which board matches your riding style.

Shared Jones Snowboard Technologies

Before looking at what sets them apart, both boards feature Jones’s signature design philosophy to maximize versatility across variable terrain:

• Directional Twin Shape: Features identical tip and tail widths for riding switch, combined with a subtle setback stance that enhances nose float in fresh powder.
• CamRock Profile: Camber underfoot provides explosive snap, stability, and edge hold, while rocker in the tip and tail prevents edge catches and floats easily in soft snow.
• 3D Contour Base 2.0: A subtle 4mm spoon bevel at the nose and tail that lifts the contact points off the snow, making turn initiation fluid while reducing drag.
• Traction Tech 3.0: Strategic serrated edge bumps along the sidecut that bite into firm snow and icy groomers like a steak knife.

Jones Mountain Twin vs Mountain Twin Pro Comparison

Jones Mountain Twin Review: The Everyday Resort Daily Driver

The Jones Mountain Twin is designed for all-mountain riders who want one quiver-killing snowboard to handle everything from morning groomers and tree runs to side hits and park laps. Its forgiving flex profile makes it approachable without sacrificing high-speed stability.

A versatile, medium-flex directional twin built for intermediate-to-advanced riders seeking effortless turn initiation and playful freestyle pop.

Key Specs:

• Flex: 6/10 (Medium)

• Core: Control Core with Biax Fiberglass

• Base: Sintered 8000

Highlights & Key Features

• Forgiving 6/10 Flex Pattern: Easily manipulated at lower speeds for presses, butter tricks, and quick maneuvers through tight trees or mogul fields.
• Biax Fiberglass Weave: Offers smooth, predictable torsional flex that reduces leg fatigue during full-day riding sessions.
• Sintered 8000 Base: Durable, easy to repair, and holds wax exceptionally well for consistent glide across varied snow textures.

On the snow, the standard Mountain Twin shines through its nimble turn initiation and energetic personality. The medium 6/10 flex allows intermediate to advanced riders to load up the tail for snappy ollies off side hits without requiring brute-force leg power. When maneuvering through tight glades or choppy snow, the board reacts instantly to subtle toe and heel inputs, letting you switch lines effortless on the fly.

Because the torsional flex is relatively forgiving, this board won’t punish you if your technique strays off-balance landing a jump or carving on late-afternoon slush. It provides a sweet spot for riders who want an engaging, comfortable ride that doesn’t leave their calves burning by 2 PM.

Jones Mountain Twin Pro Review: The High-Speed Charging Monster

The Jones Mountain Twin Pro takes the classic directional twin geometry and supercharges it with aerospace-grade dampening materials, carbon reinforcement, and a race-grade sintered base. Built for aggressive, power-focused riders, this board is engineered to eliminate chatter and stomp heavy landings.

An ultra-stiff, highly dampened freeride twin engineered for advanced riders who demand maximum response, explosive pop, and high-speed stability.

Key Specs:

• Flex: 8/10 (Stiff)

• Core: Koroyd Core with Carbon Stringers & Triax Glass

• Base: Ultra-Fast Sintered 9900

Highlights & Key Features

• Ultra-Stiff 8/10 Flex Core: Features Koroyd inserts in the tip and tail alongside structural carbon stringers for maximum torsional stiffness and explosive energy transmission.
• Triax Fiberglass Layering: Multi-axis glass weave that holds an unyielding edge lock during high-velocity carves on bulletproof snow.
• Sintered 9900 Base: A high-density, ultra-high-molecular-weight base that hauls through flat cat tracks and wet spring snow without losing momentum.

Riding the Mountain Twin Pro is an exercise in pure power and precision. The addition of Koroyd in the core dramatically lowers swing weight while absorbing high-frequency vibrations before they ever reach your feet. When pointing the board straight down steep, rutted groomers or stomping off massive park features, the Pro feels rock-solid underneath, it simply refuses to chatter or fold under pressure.

However, that aggressive stiffness means the board requires active, technical rider input. At lower speeds or during casual cruising, the Pro can feel demanding to steer and resistant to slow-speed buttering. This is a precision instrument built specifically for heavy hitters, larger riders, or expert snowboarders who ride fast, charge hard, and need absolute reliability on steep, technical lines.

Key Differences Breakdown

1. Flex Rating & Torsional Stiffness (6/10 vs. 8/10)

• Mountain Twin (6/10): Features a balanced, lively flex pattern that bends effortlessly into carves and presses. It provides a comfortable, playful feel that won’t exhaust your muscles when lapping the resort all day.
• Mountain Twin Pro (8/10): Substantially stiffer both tip-to-tail and torsionally. It requires precise technique and leg strength to drive into deep turns, but rewards aggressive riders with instantaneous edge response and unmatched stability.

2. Materials & Core Construction (Carbon & Koroyd vs. Biax Wood)

• Mountain Twin: Uses a full wood Control Core wrapped in standard Biax fiberglass. This setup delivers a natural, springy wood feel with plenty of snap and dampening for everyday resort riding.
• Mountain Twin Pro: Upgrades to Triax fiberglass reinforced with carbon stringers and featherlight Koroyd in the tips. This high-tech construction drastically cuts swing weight while providing unmatched shock absorption across rough terrain.

3. Base Speed & Glide Performance

• Mountain Twin (Sintered 8000): A highly durable, premium sintered base that glides smoothly across cold powder, packed groomers, and spring slush with minimal wax upkeep.
• Mountain Twin Pro (Sintered 9900): Jones’s fastest base material. It holds wax noticeably longer and accelerates effortlessly, giving you the extra speed needed to clear big jump tables or coast through long, flat cat tracks.

Final Verdict: Which Board Should You Choose?

Buy the Jones Mountain Twin if:

• You want a versatile, approachable daily driver for all-mountain freestyle riding.
• You spend plenty of time hitting side hits, buttering, and lapping terrain park features at moderate speeds.
• You prefer a forgiving flex that doesn’t require aggressive physical input to initiate turns.

Buy the Jones Mountain Twin Pro if:

• You are an advanced or expert rider who charges at high speeds and stomps big airs.
• You need a rigid, carbon-reinforced board that eliminates chatter on icy groomers and steep freeride lines.
• You want a supercharged sintered base and featherlight swing weight for high-velocity riding.
