Hi Pete,
Don't mean to step in before Woody but being you mentioned Bear heads, I recall having a snare head made by that company. It was black, and having a cross hatched texture fiber that was very durable. I actually gave it to a club that had a Yamaha house drum kit set up on stage. There were at least three different bands performing there in a weeks time. I do remember that it lasted over a year before they replaced it. Just thought I share that morsel here.
My apology Woody. I anticipate hearing what you have to say about it.
