I have only handled one. It was a hunting rifle stock, the one with the straight comb.
Looking at Manners website, I think it must have been this one:
It was very stiff in the forend -- I was impressed.
I prefer a more open grip, but that isn't a criticism, just personal preference.
Looking at that picture, there is a lot of cast but I did not have a chance to shoot the rifle I handled so I do not know how recoil would feel.
