I have a with problem flat bands, Every time I make a single layer bandset for target shooting, they break within hours, when I have only shot it maybe 10-20 times. It always breaks at where it connects to the pouch. Its not that I did not tighten the string or rubber bands enough, its just that it always snaps there. I thought it was because the roller cutter I was using was not sharp enought and that it wiggled around a bit, which cause inaccurate and small tears in the rubber. I got a new one and it cut perfectly, but even then I'm still having the same problem. the band snaps at the same place! it is incredibly frustrating. I'm sorry that I can't provide any pictures now, but if you understand and have had similar problems, please share. Thanks!
