I really appreciate all the input and advice. I am pretty sure that keeping a sniper rig in tune and building one can't be any more difficult that keeping a high end dual cam target bow in tune or keeping a high performance RC sailplane in tune. As nice as the WA2000 is I would probably go with the DSR-1.
If we go this route we will end up working as a sniper team. The run and gun style isn't for us. For that we would stay with playing speed ball. We are looking more at a precision shooting style of play.
Maybe we should just do what one of the helpful folks have suggested and go with pump style guns and stay with PB.
