r .75 is pretty good if true for .125", that's I think r .25 better than evazote if actual.
really want to see your thicker pads, I hate neoair more than any pad I've ever used, possibly even more than old style 3/8 ccf, so it's time to start exploring old school thick closed cell again I think.
But worth checking out the 1/8 in the meantime, so I'll probably get one too.
By the way, is this sort of soft and flexible like evazote, or is it a bit stiffer and less flexible, like plastazote?
A cut down piece would weigh around 3oz I guess, that's 72x20, but I like you are doing bigger pieces, the scraps are really useful for other stuff.
