I can compare them to a couple different skis I've ridden, hopefully it helps out a bit. I had pocket rockets a couple years back, and although people seem to compare these two they are way different. The mojos are much stiffer, a bit slower edge-to edge, and have a much longer turn radius (which I find to be really nice at speed). I've also ridden Karmas and I found those to be softer than the heads as well, although not by a lot. The turn radius is similar on those two, but I think the Mojos are still a bit bigger. Overall they're great for going fast, they're super stable, and you can still go into the park with them if you want. Definitely geared more toward actually skiing, so if you're a park rat I'd shy away from them.
