I started with a JBL carbine back in '88 and "graduated" to a JBL 38 Special NW when I got out of college. I still have both of them and used to think they were the cats meow. They are retired now.
With the little one band carbine I actually bounced the spear off of rockfish and Cabezons at close range. Zero penetration.
I am glad I have nicer gear now!
