Frank, I have, but now tend to use plaids and older style woodland camo. Never used limbsavers and didn't say they don't work.
I do feel that a proberly tuned bow and a reasonable weight arrow set-up will be quiet! It seems like people sometimes try to "bandaid" a set-up or won't take the time, quick fix.
As far as being new, Pearson used mercury capsules on their bows for a time.
Me, I would rather spend that money on arrows or better yet, save it to someday purchase one of your Fine Knives. Good shootin, Steve
