I rode Eric's 1000 and Rosie's SXR powered Q8's. I thought it was a fun ride, for a few minutes, but I would not rush out and buy one. I think if you just wanted to do flatwater flips it would be a much better investment than a big motor simply b/c the hull wants to flip, it is shorter and only weighs 60lbs. It is stable from side to side but as waterfreak said, don't plan on riding in the surf with it. Even though it has the sxr stability in some aspects of its design, it is still a 60lb hull that pops out of water. I think it would be too twitchy out in the ocean. But all that aside I think it is just to purpose built for my liking. I could see many tricks being lost or extremely challenging on a set up like that. I'm a big fan of the old school hood tricks, bull dogs, subs and combos. I just see those being lost in translation when you start chasing down the coveted flatwater backflip.
If all you want to do is flatwater flips and big rolls then the Q8 is an excellent choice........... probably the best. But if you want a boat that can do that everything well I would just stick with a superjet based hull. If you want a superjet that will flip better, just take 2in off the rear and your good. If you don't have the power, just hit a small wake
