Boxerdog,
I probably missed it, but are you investigating a limbsaver to mitigate recoil or for increasing length-of-pull?
Because of a large frame and long arms, my standard practice many years ago was to put a recoil pad on a newly acquired rifle. Suited me just fine, but some (actually most) folks don't like to see the rifle altered for a pad.
I have a couple of Marlins that I shoot and have found that one of these does a fine job. I add a cut to fit hunk of flip flop sole to the inside to give it a bit more LOP.
Just a suggestion:
