hello, Long time martin shooter, but first timer to this forum.Have owned martin bows since the early 80's and will own nothing else. I am in the market for a new bow and am a bit confused as to what to order, onza 3 and cougar pro are standing out, but with the onza being a gold series i am a bit sceptical that i am not getting as good a bow as the pro series, even though all the components look the same as the pro series bows. could someone tell me if the pro series have an advantage or is this what martin just randomly selected? I currently have a single cam rage that is past her years., thanks
