I think your suspension on the RR is great. I am finding more and more that whoopie slings are a pain in the rear. Take a 13' bridge, not add 8" for locked brummel then 10" for the bury and you got 36" added to your minimum hang distance. So even with your whoopie right up against the tree and as short as it will go your still looking at 16' minimum distance.
