Mostly skills. I do a fair amount of mountainbike riding and the Monty does wonders for finesse. I just set up some logs and goof around. I don't have a trials motorcycle (yet...) so can't comment there...but my slow-speed noodling around on other bikes is much better. I'm short so it all helps on my XR400 due to my short legs; I like the slow speed practice. I think I'd be better off on a 26" versus my Monty 20". I've got a short torso and the long top tube on the Monty gives me fits as a result. I could build up a small or XS jumper/urban trials pretty easily and probably have less frustration. Another plus with a 26 is being able to fart around on trails as well as the backyard. That said, the Monty is a total hoot to ride. If I do sell it, if the trialsmodgods don't disapprove I'll post it in the trials FM.
