Controversial topic Ron, but like it!
As you said though I think it is personal preference and simply what works best for you as an individual.
I too have tried so many different styles/tactics and bow types..
I wanted to love Hill style shooting and ASL's at one point but at this point just dont think its for me..
I tried getting into ILF's, string walking, just all around high tech trad shooting and it wasn't for me either.. I was just thinking way too much into things.
I just enjoy shooting all sorts of recurves and DR longbows, and love a beautiful wood bow!
My shooting style has evolved or changed over the years for sure, but still consider myself to shoot "instinctive." I know instinctive is a controversial topic, but regardless of arrow length I pick a spot and shoot, whether or not I am subconsciously referencing the point who knows, but broad heads, FP's or blunts don't seem to effect me.
I shot split finger for nearly 15 years and it worked for me! A few years ago I tried 3 under and haven't looked back... It put the arrow closer to my eye and allowed my "instinctive" style shooting to perform better at a little longer range as I could "sense" the trajectory better if that makes any sense??
Owen Jeffery taught me how to shoot starting as a child.. He made me the hunter I am today, and really made things simple. He himself was one of the best shots I have ever seen! He shot split and "instinctive.." He didn't emphasize follow through to the shoulder or anything like that but just taught me how to shoot a bow like I was shooting a slingshot and I killed a lot of critters! He taught me to not pluck the string, which in my opinion this the most important beginning lesson to any archer.
However, over the last few years I have really been paying attention to PUSH podcasts, Tom Clum Sr., Joel Turner, etc. and what a difference it has made for myself. No I don't necessarily think there is one right way to shoot a bow, but dang if their style of instruction didn't work to make me a better more consistent archer! I'm not a clicker shooter, but use the feather to nose as my "trigger." Not everyone is like me but in my mind keeping a low bow arm and expanding with your back on the draw arm (ie. Followthrough) just works, and made my groups tighten 3 times.
