I've been tuning some arrows for my Tall Tines and discovered that when I do a lot of shooting I get some spots on my hand where the handle irritates it a little. So, I studied it a little before I started sanding, but I tweaked it some to settle my hand on into the grip.
The wrist was too high for me and I took some of that down to start with. I have not held another Tall Tines, but I imagine what I done was to make it into a "medium". Then just worked on the front of the riser to settle each finger in it's natural place. I like a grip instead holding loose, not too tight but a grip.
Anyway, it helped. I thought you might want to see some shots to see that I didn't ruin it. :D
This shows it in my hand held rel loose so you can see. One place that was irritated was the top of my thumb joint. You can tell I raised it up a little.
I thought long and hard about this before doing it. I'm not recommending that anyone make changes to their bow themselves. It's just that I intend to have this bow till I drop. Plus I have some experience shaping handles.
