+1 on the Limbsaver pullover pads. Unfortunately my hunting buddies (?) introduced the term "butt condom" to describe them, and it stuck....
They do lengthen the pull some, and that might be a problem with some guys on some guns. I have what my gunsmith describes as "ape hanger arms," so I need the extra length on most guns anyway.
If you hunt in the rain with the pad on, make sure to pull it off and dry the stock and the pad out after you get back.
