Thanks again, LCPullman, I will look at the link...speed, however, is not important. I don't have speed, but would trade it for 'eveness' if I could. I need the reverse to get out of situations on a hill, even power is what would work best for me, speed would likely spin the wheels. maybe I'm egtting caught up in words here (speed, power, etc) but I think you know what I mean to say. Thank you.
