Same old Wonk. LOP doesn't make a bit of difference . . . nope, doesn't make much difference when you're shooting nothing but targets, pre-mounted. No more than gun weight matters, when you're only toting the gun from the trunk of the Mercedes to the 16 yard line.
If one accepts the late Gough Thomas as a "published authority" on shotguns, here's what he says: "Since our leading coaches and gun-fitters cannot always agree on what constitutes the correct stock for a given man, I beg to be acquitted of any intention of laying down the law on the subject." It would seem that Mr. Batha, who is a coach, has as much right to submit his opinion on the subject as anyone else--given the lack of agreement to which Mr. Thomas refers.
