It doesn't matter as long as it is a Mathews they all shoot well...J ust ask ROB/PA ( hoyt shooter )lol..I'm adding to this post from yesterday,I had the pleasure of shooting the switchback today when I was picking up my son's new bow that I got him for Christmas( he's 8 ) and I just put money on one so I can pick it up after the holiday's..It's light,well balanced and extremely steady. We chronographed the speed at 310fps out of the box at a 29 inch draw....If you shoot it once you will buy it..I warn you if you go and shoot it leave all credit cards at home lol....
