T, I did some experimenting myself with the Dloop length and I found that too long made me stretch my bowarm too much and shortening the draw made me lose my anchorpoint.
I forgot to mention that after my surgery I have a "blind" spot on my cheek where I can't feel enough. I had to change it further upwards and now I have my thumb under my ear.
Tomorrow if the weather permits, I'll be shooting outside to get better footage.

I was hoping to hear from you, you have one of the cleanest shots I ever saw....

thx
