Im pretty new at setting up my own bands. Im using tbg and I also use the tbg calculator on this site. Im having problems with my bands snapping right at the pouch and my bands get messed up right at the pouch. It's hard to describe so I'm just going to put pictures up. My bans broke the second time using them. It just seems like I should get a little more life of of them. The first picture is the band ripping an the second is the band twisting I guess you could call it.
