In all fairness he is a PNW shooter and just MDed a 2 day PRS match in Idaho. If you saw the wind (and fire) at that match , square east coast it was not. I don't think that's the right application here even through I do think the RRS has some advantages over the 2 Vets from a pure gamer and ergonomic perspective.
Everyone uses gear different so what may be an advantage for one guy, another doesn't care about.
