Drum Springs for my SP20

Quick question about replacement springs on my SP20. The press is currently on long-term loan to a friend, and since their adopting it, we have now broken 3 drum springs in less than 3 years. I know at least one of them was an hardware-store spring which happened to work, but one, maybe two, were from NA Graphics. 

It’s always the same one (motor side), and they’ve only lasted a what feels like a few months, likely a few thousand impressions. 

Any suggestions?

I spoke to Kyle and my only thought was the drum arms were set too low stretching the springs at all times. The cam is part of the arm.
