Lloyd,
I agree with your thinking about the "roll" mitigating recoil in single actions. I found that I got a better grip on the Hunter model with the Hoage's. I don't Know why Ruger thought they needed to put that bull barrel on the hunter models. That weight plus the scope I was having trouble holding it steady, comfortably. I seemed to be fighting the grip to steady it. The Hoage gave me a more comfortable grip to steady the up front weight of the gun. I never considered the recoil aspect as it's never bothered me.
Yes, they are ugly, but they work for me.
