Hey bud, from what I've read on this forum you want to shy away from the two speed. Read the thread about why do the gears strip out...there is a lot of info on this forum and my memory won't let me tell you exactly where to look, but it is here. Hunt and read and you can glean a lot of info from the threads on the firs page. Ehroof, popper and the chubbys (uncle and dad) along with several others will set you straight. I didn't leave anybody out on purpose here, just can't remember them all. Read around and ask questions and welcome to the forum.
