You are fortunate to have several bows that you shoot very well. I'd say it's because you match up best with them physically and mentally. I have had a number of bows at any given time, but always as I got within 1 month of elk hunting I shot only the bow I was going to use that season. That helped clear the inconsistencies I would experience for a time when I switched out on bows. That being said I do have one longbow I use exclusively for shooting carp but it is only 5# lighter than my hunting bow. I still have a favorite takedown recurve with 3 sets of limbs that will cover all of my hunting and shooting requirements and although I have not shot it for some time; like you indicated with several of your bows, I can shoot it fairly well anytime I pick it up. It stays as my backup bow should the need arise. When I have a bow that I don't seem to shoot well, I sell it, as I admit I am not that great of a shot anyway. I understand what you are saying though. Best to you.
