The Future Spin is kind of the step up from the Afterbangs, which are meh. This year they were semi-re-designed and got much better. I had a pair of 2(?) year old afterbangs. They held up great, I slammed them into concrete, rails, ice, dropped them off of roof's, ski lifts, and walked across my hill's dirt parking lot with them. Durable as fuck.
I also have this years Chronics. From what I've skied so far, they are awesome as well. Pretty playful but kind of stiff I suppose. They rip all mountain and the rocker has been great on the last few storms. There are a few other skis that I may have chosen, but overall am really happy.
That being said, like I mentioned earlier the Future Spin seems to be a re-designed newer Step-Up. Mostly park oriented, can take it pretty deep, pretty stiff, a good rail/jump ski, 'meh' all mountain though. The Travelling Circus is your other option for a middle ground ski, which is very soft, 'playful' and 'buttery'. That being said I don't really like them. They are like soft, floppy, flimsy spaghetti noodles. Compared to the Blends, Chronics, and Future Spins.
