How many of you of you use a Bell Carlson Stock? Are they good, bad, or just so so?

Building a rifle in stages, got a Savage 12 action with a SSS trigger on the way that I bought on another forum, when I get some more money I am gonna get the Barrell , then a stock. Will be building a 6BR.

Will shoot alot off a bench from 200-500 yards with a small group of guys and will shoot the occasional hog or coyote at those same distances.

This is the one I was looking at:

Does anyone have any thoughts on a thumbhole laminate?

Thanks
