I really wish you'd tape a Jones pad or something on your current gun ...and snap a few photos.../ ....it would at least be good for a laugh.
Here is a picture of my fine stock smithing, another of the gun mounted with the pad lowered just less than an inch, and a third with the pad back in place. I lowered the elbow of my strong arm so as not to block the view of the mount. Note how lowering the pad to increase drop at comb increases distance from nose to thumb. It also seems to take a lot of pressure off of my neck.
