RE: OPTIMA ELITE OR PRO ACCURACY
Optima Elite if you want to put centerfire barrels on. Optima Pro if you don't have any intention of using it for centerfire.
I love thumbhole stocks, however, the plain jane stock that came on my optima elite felt so good that I opted not to put a thumbhole on it. Besides, they are so inexpensive to get new ones, should I opt to put one on later it won't be that big of a deal.
