Very good points to be aware of
I have just received a stock I ordered from Martin that has the 2 parallel flats.
View attachment 535172 This is why I switched to the flat top...for better free-recoil path..although from my few observations ..that stock is not moving
I did choose the widest spacing between the ears for this stock which was 3/4 inch and have the medium codura ears that i rubbed some HBN to keep it slick.
It's a little messy, but does a nice job...still need to test how it works if it is wet.
Appreciate all the advice
Question:..How tight are you filling the bags? ..I have mine as tightly packed as i could get it. The ears are not as tightly packed .
i figure that one would want to eliminate variables that a softer bag would present
