Another Bear Paw Classic guy here.

TP can and will absolutely affect a true instinctive archer - been there, had that TP affliction.  As we all know, TP is a 100% head game, and as such it matters not what's used or not used as a "bow sight". 

It's about what triggers releasing the fingers off the bowstring, no more or less.

Whether or not you see only the "target spot" ("true instinctive aiming") and/or some physical object on the bow or arrow that's in some manner aligned with the "target spot" doesn't matter at all.

Something has to trigger letting go of the bowstring fingers.  With Olympic Recurve target archers it's the "click" of a clicker.  With "soft sight" trad bowhunting it's some manner of physical alignment (i.e. - arrow point, string, riser, shelf, whatever) and then the brain sez "release!".  With "pure instinctive aiming" it's the brain saying "all systems are go, let it go!".  That trad bowhunting release point can be negatively influenced by bad (or no) brain control (whether conscious or subconscious) = TP.

Good job on your hunt. I shoot instinctive. I've had target panic on occasion. The only way I can explain it is something was off in my mental cycle when I drew the bow. Mostly, I didn't pick my spot or maintained my focus on it. At that point for me it's like putting the cart before the horse if I try to correct at full draw. I just can't make it work. Best to let down and start over. One thing that helps me, especially hunting, is seeing the flight that arrow is going to take before I even draw. It's not something I really think about. I guess it's more of a a confidence thing. I do however have trouble with my mind wandering when typical target shooting. That's why I enjoy roving through the woods and picking different things to shoot at. That way I don't get frustrated.

Yes, very interesting book.  A lot of great information in it. 

For heavy bows, I like Bateman.  For bows a littler lighter, I like American Leathers.  Both companies have several models to choose from.

My lovely wife is so thoughtful it is amazing! She found a copy of this book on eBay while looking for something else entirely. She has zero interest in archery other than it keeps me out out her hair, which is important. As a bonus its an author signed copy as well.
Having grown up in Michigan, Fred Bear was the man around these parts. As an adult I was aware of Howard Hill, but not in any real detail. I'm sure the wife probably heard me babbling on about Howard while watching Robin Hood or ??, and thought I might like to read it.
The book is loaded with pictures which are historically interesting and the details of his archery exploits are nothing short of incredible. The 85lb draw weight he routinely shot and 115lbs used on elephant is definitely legendary in my book! Sheesh thats a lot a weight! Been a fun read!

Those shirts are very nice!

A little slow to the party, but 3 Rivers Dura Glove for me!
