Guys, when I started shooting as a teenager, I shot split finger anchor with middle finger to corner of mouth and top knuckle of thumb in jaw "divet" under earlobe. I don't remember ever having problems with this.
Then several years back I began noticing two recurring problems which led me to make some changes.
The first problem was that the string was stinging the tip of my nose with almost every shot.
The second problem was that the middle finger/corner of mouth anchor just seemed like a strain. Just...a strain (even with a lighter bow). However, amazingly, I found that by anchoring with my INDEX finger/corner of mouth, I got that feeling of a let-off as if I was no longer holding bow weight, and on release, hand moved straight back opposite the motion of arrow feeling like a slam dunk. All that by anchoring with the index finger.
To correct these problems, I eventually shortened my draw quite a bit, began anchoring with index, and switched to 3 under hold to fix the change in point-on distance with the index anchor. These changes yielded a loss of a secondary anchor point as my thumb-tip was now also holding my pinky-tip in place; and I've shot for years that way ever since, having no secondary anchor. I have always been very accurate.
Fast forward to now. With the new mirror set-up in the living room, I was looking behind me while drawing and realized with the shorter draw length (25") I just am not getting my forearm and arrow into a straight line, but by drawing to about 26 3/4" my form is just textbook: Arrow and forearm form straight line parallel to shoulders, and arrow speed increases dramatically with the longer power stroke. ALL great things. So, I definitely want to shoot with the longer 26 3/4" draw, since it achieves proper alignment.
For reasons of my own, I also want to return to split-finger with middle anchor and standard thumb knuckle secondary anchor.
BUT NOW,
I have the same two problems shooting split-finger/middle anchor I had years ago: middle anchor just seems like a strain and the index anchor just feels soooo good. Also, the string just seems to be hitting my nose no matter what I do (I'm actually a bit raw today).
Anybody got any ideas? I've about exhausted myself.
