My primary focus is in the WA3D "instinctive" division so I stay with a fixed anchor and my finger has to touch the nock.
So, whenever I shoot longbow, barebow or my hunting bows I do the same, my mindset in anything to do with this game is to simplify and be as uncluttered in my head as is possible.
What I have done, particularly for competition is to manipulate my point on and sight picture (up to and within 32yds for official tournaments) by adjusting my anchor (as high as my glasses allow), arrow length (as long as possible), nock height, arrow & point and draw weight. I now have a POD of 29yrs and an 8" max gap. My arrows are not too heavy that they done drop off too much beyond that 30yd distance either.
My hunting bow is nearly identical with the extra weight on the limbs and arrows. Longbow/woods is a bit of a struggle doing it like this but I only dabble in that for fun and longbow safaris and the like.
I set a barebow up for indoor this winter and I did it all with the arrows. Big, aluminium hernia poles, 300 up front and half a turkey at the back. point on at 18m.
Over the years I have tried lots of different solutions to tighten my sight picture, I believe it very important in the division I shoot in, and I'm happy where its at now. I draw 30", Mins 23", Uukhas 38#@28, B.E. zombie slayers 400s at full length with 120gr glue ins. Any lighter and my max gap is too big, any heavier my arrows drop like a stone.
