I own, mainly, one brand of bow, Schafer Silvertip, does that count, LOL. Yes, some cannot afford more than one or two,and that is fine. Me, I can afford it and there is no reason for me to own just one, I shoot each the same and can pick up any of them and be in the woods ready to go, same arrows for all of them. Only other I have right now is a custom Huntsman, and it shoots the same arrow as my other bows. Life is too short to own only one bow.
In my lifetime I have owned over 300 of most of the top of the line custom bows out there.
