I’m in the same boat with Gab. I’ve nearly pushed the “ Buy It Now” button several times. But I know WWB already tests my arrows in more ways than I could. With the RDX 400 and TP 505 I know arrows fly fast enough. Using speed as a way of judging string life or other maintenance issues seems to have some merit. As Gab said “All that said…” seems like the only thing I really care about for my type of use is whether hunting tips hit where I aim. I’ve moved my money into hunting tip targets.
