Holograms are very responsive, they just give a different feel tip to tail. Its more of a skate feel. But they will hold their own on stiffer decks, provided you like the looser feel in the heelcup. The DMCC Light is just barely below a freeride performing binding, responsive and light as shit. The NX2 SE's are stiff, the hybrid strap does work well and it will be better for someone searching for pow than the I-Strap. The Company is K2's stiffest binding and quite fantastic for what you're looking to do.
Go ahead, drink that kool-aid.
