While I've got several makes of bows, I think it is best to stick to one bow, or closely matched bows of the same make and model. We all eventually learn some degree of accuracy within our limitations, which means that we learn to do the same things RIGHT and the same things WRONG consistently and repeatably. (Ever watched a guy shoot the nocks off his arrows but badly plucks the string every shot?) Adding the variable of a different bow changes the equation.
I know a lot of guys are content to shoot 15-20 yards, but many shoot no further because they can't. I work to have consistency at variable ranges, and that requires consistency in equipment, unless both me and whichever bow I'm shooting are perfect according to the laws of physics, aerodynamics, and the like.
Now, I'm not a very good shot. I am sure that many who post here could flat embarass me in a shootout. But I idealize myself as someone who wants to emulate Howard Hill and Ben Pearson (sp?), and Byron Ferguson as role models. These, and many others, set a high standard as repeatable accurate archers and bowhunters. And I doubt they were using different bows every day. I think that in our "lust" for some new, prettier, different bow, we end up with a safe full of different bows that won't shoot for us if we get out beyond the 20-yard range.
Also, I'm a gap shooter and don't get much into the "instinctive" thing, and that says a lot. I'm not comfortable shooting a bow simply by feel, because I want repeatability, and don't want to have to be "dialed in" in order to shoot accurately. The instinctive shooter probably has a different opinion on this than me, but I want to be confident that if I get one 45-yard shot all season, I've got both equipment and a technique that are consistent enough that I can make that shot... the first and only chance I get.
That being said, I shoot Black Widow bows. One recurve, and one longbow.
