I don't know about the rest of you, but I find having to rest the stock of the typical springer across my palm both awkward and hard to control. Glad I have a CFX. But since Charlie has my CFX, I've been shooting my freinds Shadow. Although I finally figured out how to hold it so that it would mostly hit where I wanted it to, it was still awkward for me. Then I remembered a suggestion someone had made on a post somewhere. Use a computer gel pad. So I tried it, and son of a gun, it worked! Even though I'm still trying to get the feel of this particular rifle, I was able to shoot a half dozen consecutive 1/2 inch groups at 25 yards. That's about the same as I was doing shooting with the rifle rested on my palm, and I don't even want to talk about the "groups" I got shooting of my sand bag. So maybe the gel rest that Pyramid Air sells would be worth trying, but steal the gel pad from your keyboard or mouse rest first to try.
