I like that stock, would'a bought it if I saw the post.
On the mount, yes a good mount helps, but if you happen to be not "average" in build, sometimes a stock like this is the difference between good shooting practices and bad.
I'm tall with long arms and big hands, and I like this stock with a large palm-swell pistol grip, it is comfortable and it allows me to get a good natural point of aim without craning or muscling things into place. When I owned a few PRSs, the LOP and riser were always adjusted.
Just a counterpoint. I agree a good mount goes a long way, but the mount don't change the shape of the stock or the shape of the shooter, sometimes an adjustable stock is needed to effectively mesh those 2.
Scream'in deal, enjoy the stock.
