Great idea! I played around with a similar idea several months ago on my claytor no net. It really does help! I did something different for the ridge line---just a simple continuous loop in a prussic knot around the whoopie sling end, with the ridge line attatched to the loop. (that way you can adjust the ridgeline up or down on the whoopie is needed. ) I thought your idea was pretty creative though! I was using a piece of wood for a spreader--I think the pvc idea is brilliant!

Do not walk behind me, for I may not lead. Do not walk ahead of me, for I may not follow. Do not walk beside me, either, just leave me alone.
