Because vertx decks can actually be trusted. They have flat sides and are the best deck you can get for grinds. If you break your headtube all you need is a new one. You dont have a piece of shit plastic break. They whip and all around feel alot better. Forza/xray combo is my favorite deck ive ever ridden. And if you break anything, itll actually get replaced. Vertx is all around better.
