Yeah... if your planning to do alot of trials the Qu-ax with the splined hub is the way to go, it's more expensive but in the long run worth it (less broken parts). as always if you can save up 500 (canadian) dollars go for the KH 2005. but i have heard that the Qu-ax with the splinded hub is good for up too 5 foot drops, no personal experence with either but yes... totally save a little bit longer and get the Qu-ax
