YES Greats UnInc Review: The Best Carving True Twin for Freestyle Riders

Introduction

Some snowboards get described as the best carving true twin on the market, and in the case of the YES Greats UnInc it is genuinely hard to disagree. This is one of the most versatile freestyle boards out there, and it keeps earning a place in best-in-test lineups year after year.

While it might look like an all-mountain board at a glance, it sits firmly in the freestyle and park category of the YES lineup. That said, once our test team straps in, nobody wants to take it off, no matter what they are riding or what the conditions are doing. It has been a staple of the YES line for years, and its shape is unlike anything else on the market.

Who This Board Is For

The Greats UnInc suits riders who want a freestyle-first board that does not give up carving performance. If you spend your days between the park, groomers, and the rest of the mountain, and you want a board that feels just as confident switch as it does regular, this is squarely in your territory.

It is also a good match for riders who like a board with some backbone. The camber profile and stiffer flex reward effort, so beginners may find it demanding, but intermediate and advanced freestyle riders will get a lot out of it.

The Asymmetrical Sidecut Explained

The Greats UnInc uses an asymmetrical twin shape rather than a true twin outline. Split the board in half through the center and the shape, flex, sidecut, and stance are perfectly symmetrical nose to tail, exactly what you would expect from a park and freestyle board. Split it down the middle and compare the heel side and toe side edges, though, and things get interesting.

The heel side edge, which is always the heel side edge whether you ride regular or goofy, has a much tighter and deeper radial sidecut than the toe side. That tighter sidecut generates more drive and grip through heel side turns, effectively balancing out the biomechanical advantages of toe side turns and creating the same turn experience without working any harder.

Come in even closer and the asymmetric mid bite becomes visible: the sidecut pulls in at the waist between the inserts on both edges, with the heel side concentrated in an even smaller area. The narrower waist lets you torsionally twist the board more efficiently for quicker, more reactive turns, while the wider platform underfoot preserves stability and surface area.

One practical note: the Greats does not come in wide sizes, but because of the sidecut geometry, larger-footed riders will be fine on the bigger sizes. And while the shape can look intimidating on a wall rack, on snow the result is clean, simple, and effective. Whether you are setting up for a frontside spin or railing a carve on hardpack, it works outstandingly well. It turns better than some directional boards out there, and it will do it regular and switch.

Construction and Flex

The shape is only part of the success story. Under the topsheet sits a high-performance core with a camber profile where, compared with something more entry-level like the YES Basic, the camber sections are more pronounced and the rocker sections less so. The trade-off for that slightly looser, forgiving feel is a board with a ton of pop and rebound that lets you attack the mountain.

The flex rating is a 7 out of 10, and that feels about right. That is where most high-performance all-mountain freestyle boards sit: stiff enough and responsive enough to handle higher speeds and forces, but not so stiff that it loses playful freestyle versatility.

The wood core blends three different wood stringers: poplar, polonia, and bamboo, a mix aimed at strength, low weight, and pop. Carbon fiber and triax glassing sit in the layup, which means the board takes better work to get the most out of it, and a quality sintered-style centered base caps off a genuinely premium freestyle construction.

Worth a mention too: this year’s graphics from long-time YES artist Kalonji. Pull out the entire 149 to 159 size range and they fit together into a single canvas, which looks excellent laid out side by side.

Things to Consider Before Buying

The demanding flex and camber profile mean this is not a board for riders who want an effortless, Surf-style feel. It rewards input and technique. If you are after a soft, forgiving park deck or a mellow first board, look elsewhere.

Also, the asymmetrical shape is the whole point of this board, and some riders simply prefer the familiarity of a symmetric sidecut. If you have never ridden an asym board, expect a short adaptation period before the balanced turn feel starts to click.

Buying Advice

Nothing changed this year, and nothing needed to. The Greats UnInc landed a spot in the Whitelines 100 again for this season, and it remains one of the best park boards we have ridden and one of the best turning experiences on snow, full stop.

If you are an intermediate-to-advanced rider who wants one board to cover park laps, groomer carving, and everything in between, buy it with confidence. Riders who prefer softer, more forgiving flex or who want a wide size will want to weigh other options.

Conclusion

The YES Greats UnInc lives up to its reputation as the best carving true twin on the market. Its asymmetrical mid-bite sidecut, premium three-wood core, and well-judged 7 out of 10 flex combine into a freestyle board that turns as well as many directional decks, in both directions. For versatile riders, it is an easy recommendation.
