I bought a bunch of the BJ Long softy bits with the intention of using them on all my pipes, more for protecting the stem than for comfort. After trying them on every pipe, I decided that they weren't for me and I am just careful not to bite down hard enough to leave deep impressions. My thought is that the pipe maker has gone to great effort to make sure that the stem and button is functional, comfortable, and enjoyable, and that is how it should be smoked. It's worth noting though, that I will not clench new pipes until I've smoked them enough to decide that they are "forever" pipes. After that, if I do leave some chatter it is just a sign that my pipes are well loved.
I ended up giving my stash of them to my dad, and he loves them. He can't clench a regular hard stem due some dental issues, so this was a huge improvement for him. Like previously mentioned above, he cut the button off of all of them with a razor before using because he felt they were too bulky as-is.
