To those of you who have ridden both the SM6 & SE6. My preference is the SE6, which I have ridden as a loaner and liked very much. Granted, I have never ridden an SM6, but I have a great chance to get a new 2016 RT SM6 for a really great price. On the SM6, does a heel/toe shifter make a big difference? My current ride is an SE5, and I really like the semi-auto shifting. Anybody have any downside to the SE6?
