Beaver,
Have you read the latest issue of "Traditional Bowhunter" magazine?
The interview with Roger Rothhaar is interesting, he says he uses two metal nocking points, one above and one below the arrow, and has two additional layers of serving where he grips the string as he always shoots bare finger, (unless it is very cold).
If I am reading the article correctly, he only double serves the string where he grips it.
His quote is:
"I use two metal nocking points (above and below) and add two additional layers of serving to the string where I grasp it split finger"
I think that means he doesn't double serve the exact nocking point, as he doesn't mention if he uses a special "wide" nock on his arrow to fit the extra thick serving.
I may try it, I need all the help I can get on my release....and my bow torque...and my lack of follow through..oh never mind.
Hope this helps.
John
