I was <that close> to the Brakeaway throttle lock but finally decided that for me the throttlemeister was the better choice (cleaner look, lingering doubt about tolerances with heated grips non-rational gut appeal) .

The "heavy" set is almost 1/2" longer(nice- for even easier tightening) and 2oz. heavier. I cant imagine that those 2oz per side would make a difference...bit I can't imagine why they would make 2 sizes if there is no difference. So other than really close lane splitting () is there any preference or functional difference?? why did you choose what you did...if you are like me MORE is always better...so you got the heavy!! (lol)
