Sumo recommended to me in an email that I could trim these progressively, like a cone, to get a softer initial hit, and in your case, more travel. I used to be a gunsmith, shaping butt pads, I'm sure a belt sander would work great on this material.A picture for reference of the sumos. If I don’t like the energy suspension ones I may just cut the bottom of the sumos making them 4 inch’s vs 5.
