i don't have one on the sb - its got its own suppressors - but the one and only reason i outfitted my pat with one is i don't like being cold. i'd rather be in the stand with a big jacket on and reasonably warm - than freezing. i can't make it 2 hours if im freezing to death. i could shoot my pat with the sts in my heavy winter non-hunting coat with no fear of the string hitting my jacket. to me - that reason right there is enough to use one for hunting.
