> Joe Gold was the first one to start using it,acquiring the material initially from NASA,according to him. I've seen things done with a G10 pin that just can't be done with anyone else's pin,but none of those have anything to do with actual pool. The stuff just can't be broken playing anything resembling normal pool,and when it does break,it's always in the undercut portion of the pin,where the thread terminates,but I've only heard of 4-5 pins being broken period. Some of it is made in flat sheets,which are then cut into squares and eventually rods. Some,like the stuff Barringer advertises,is rolled into shape,theoretically making it stronger. He also has the stuff in black,which until recently,was almost unheard of. The rolled versions also supposedly cut cleaner than the sheet rod. Tommy D.
