Sorbicoil & Limbsaver in the ticker variety. I'm not versed in what's really out there in other pads.

One thing to keep in mind, it's difficult to hit quickly with a stock that is too long, yet for a shooter/rifleman, a stock that's a bit short, is easily picked up and mastered - almost instantly.

Your shoulder position can easily and properly match a slightly short stock, but one that's too long has you struggling, stretching to grip and align the sights.

With a shotgun, snapping the gun to your shoulder should have you looking down the tubes, eye in the middle of the rib, without moving your head from erect. In other words, look at the 'target' which is called addressing the target, then snap the gun to your shoulder and you should be properly aligned on it, no head movement necessary. Bring the gun to your face with the butt in the 'pocket' of the shoulder. I submit that's very close to the way Ripp's 'new' gun fits.

A rifle that fits like this, is indeed a treasure.

Hitting seems & becomes simple when the gun fits properly.

I believe many people over stock themselves when wearing just a shirt, then a coat during hunting season really flubs things up.
