I got an old, used analog TL setup last year. I went from a total stock setup to TL, pipe, head, prop. The TL made a dramatic change in performance and was bullet proof reliable all season. I was and still am a newb around here and figuring out the install was not too difficult. The hardest part was asking the right questions. I can't think of one question that I asked along the way that someone, and usually multiple someones, didn't answer within a few hours. Charging the batt is not a big deal. Just put some quick disconnects on the cables or leave the batt in the ski and disconnect the inline fuse to the brain and you can charge it in the ski. Get a TL if you can, you'll be happy you did.
