The ULT solves one of the problems the Hyperframes had- the solenoid couldn't push the on/off pin.
With the reduced pressure on the pin, the noid can now do it's job.
And yes. You can play with the dwell a little on the Hyperframe to save some battery life.

Not really, The whole purpose of the ule is to lighten the trigger pull. Since with a hyper frame, your finger will no longer have a mechanical link to the on/off, it probably won't help at all. I would save up and shop for a retro, or x valve. Something that can recharge quicker so that you don't end up with any shoot down.
