I've always used Pachmayr Decelerators. Limbsaver ****** me off when they claim that the Win '70 and the Win '94 use the same pre-fit pad. They are close, but not exact so Limbsaver was compromising on the size. Pachmayr pre-fits were exact fits for each.
I'm leaning to the Pachmayr since the pre-fit one for my Ruger Mk II all-weather says it's for the pre-2001 stock which I have. The others don't say which one.
