Slanker: Good to see that you're implementing the TGC theory (or part of it). I hope it works out for you. Keep us updated
As for the Uli/Clamping question: Yes, in an essence, a clamping device is a lot like a uli device. Holding a Uli for a longer period of time is akin to clamping. I think it's a good idea to start with the manual Ulis first, and then after a while possibly implement clamping.
