I've suspended a mere two minutes this week. Really my balls don't seem to be getting any longer! I have a 4" leather ball-stretcher which I've started using as well though, believe it or not, I have difficulty fastening the four things and can manage three! I'm almost at the fourth, mind you. I'll get there soon.
A combination of the scrotal suspension and leather stretcher ought to put me well up there in the low-hanger league!
