I like engine brake if you are speaking of back shift? Comes in quite handy coming into corners and especially down steep hills.To take away all back shift and replace it with only braking doesn't sound great to me? Maybe, but I don't know about that?You can eliminate the engine brake on them by modifying that bearing. Much easier on the belt, harder on the brake pads though.
The sled should be a good setup, I see no down side other than maintenance on the bearing itself.
