QS, I agree with what you are saying, but most guys shoot with a peep so even with the top STS it will not be completely symmetrical becasue of the unbalanced weight. However, I believe that having a second STS would do a great deal to eliminate even more shock as you have said. The question now is how to mount it in a way that is would not interfere with the sights or aiming, because it would almost have to be in the same area as the sights to be equidistant from the limb tips. Very interesting concept though.
