Thumbholes
A friend of mine is the most vain person I have ever met. He is so enthused with thumbhole stocks and anything flashy.
I myself won't have a thumbhole. I too many times have had to change and shoot left handed on a nice deer. I practice with both and always keep shots left handed at 50 yards or so. I would never take a long shot.
I know they look cool, but definately doesnt' fit my hunting style or need.
What do ya think?
