How does the Proto ride compared to a T.Rice of the same size?
Two totally different boards. They shouldn't be grouped together.
The T.Rice is much stiffer. The only things they have in common are the twin blunted shape and centered stance.
If you are looking for playfulness, the Proto is much better. It also has more pop making it, in my opinion, the better jump board.
The T.Rice is a better all-mountain board because it is just super stable on everything. However, the stiffness means it's not that playful. Presses take considerable effort on it. It does have good pop too though, just not as snappy as the Proto.
If you like to hit everything in sight, press this, press that, butter this, jump over that and then go into the park and do the same... Proto.
If you are riding a big mountain doing cliff drops, maching down steeps, and hitting all types of jumps, the T.Rice.
