Ted, you may very well be correct. I disagreed only because I did not think a TM could be run above the pad. A member here has a 21SS with a sporty on a 300XS and posted a video on BBC of him running 102.
IMO, a sporty above the pad will be faster than a TM below the pad when the TM is below the pad a normal amount as in 2-3 inches below even on a 21. You will give up some hole shot. But, I have no direct knowledge and you may be correct.
