Yah thats the only problem, they pretty much stay detuned. I mean I'm sure you can get them back, but no where near what they were out of the factory. You can try just not detuning them, see how it is. It's a RC, so it probably won't catch on boxes really. I never detuned mine, and they worked fine. I've just heard alot of people have trouble with catching edges, but I never did. i bought the 08/09 last year off ebay, because the never models look terrible I think. Anyway, Sure, you can hit jumps with them, even bigger ones, but the landings will just be sketchy. It's fine for the smaller jumps, but you almost want a camber board for jumps 50+ in my opinion. If you want a good board that is soft and great for all around park, check out the Capita Stairmaster. It's a camber board, but it's amazing for park. All RC boards are unstable at higher speeds really. BTW, maybe look into the Capita line of the Flat Kick, such as the Capita Ultrafear FK. Overall, get what you want. The SB is an awesome board for pretty much anything. Unless you are going to be hitting bigger kickers alot, go with it; it's an amazing board for pretty much anything. Hope that helps.
