I can barely tolerate twist throttles on a quad when it involves any tight riding like woods stuff. The natural motion of the wrist when you're cranking the handlebars is to twist, same thing when you're shifting your weight, standing up, etc. It's too hard to maintain steady throttle through this. This makes it a safety issue to me, there's too many ways to accidentally rip the throttle open with a twist on a quad, and ripping around the corner is the last place you want to accidentally crack the throttle all the way open and send yourself flying into the trees. It isn't an issue of inexperience, I do perfectly fine with dirt bikes and motorcycles, but you don't move around nearly as much on 2 wheels. All the shifting around on a quad seems much better suited to something that's in a fixed position independent of your wrists.
