I am attempting to set up two old Martin's, a Cougar 11 and a Warthog "A". I have been looking for the NAP Plunger rest without luck and have been considering just going with the NAP Center rest. Then I thought, why not go with a Berger style button and flipper? I have Springees on them now, from my old pile of stuff, but as I remember, they seem to be hard on feathers. I sure do like the Plunger rest though as I have had them on my 2 old Oregon's for years. Any suggestions?
