Yep, sounds like a great idea! Although I'm not sure about securing them first. I mean if I do, it'll keep them mostly still. But if I don't... what's he gonna do? Try to move his legs around to avoid the tickle torture, and risk hanging from his tied and cranked balls? His options are pretty limited already, and it may be more fun to watch him realize how limited his options are, don't ya think so?

Oh and the review you mentioned, I think you're referring to the e-stim guide and review of e-stim accessories post I did a while back...but that was with Gboy, not this sub. ;-)
