I am about to buy a Giant XTC2 and it comes with a RockShox Dart 3, 100mm w/Lockout. I road it in the parking lot and it just didn't feel good. I weigh 230 right now and probably wont get down below 215 for a long while. Originally I was going to be buying a used Yeti that came with a Fox Shock but that fell through. I now have 300 extra dollars to spend on the XTC2 and want to get a better Fork. What should I get? I will be riding in Florida and I don't think there are any "big" jumps around unless I make the long drive to Santos. Having a lock out is a feature I like becuase I will using it to commute as well and need to be able to just get the power down to the pedals to get to work. I've looked at some of the manufacture sites but not quite sure what would work best because I am new to the MTB scene.
