Thank you. I have been using the 2139 for a couple of weeks, UI disabled. It feels faster then other roms, and in contrast to the most current 6.5 betas it is usable.
But in the long run, I hope we will receive the improved scrolling from 6.5 at the speed of your hybrid.
btw: Exchange email works, but setup of POP/IMAP account is not possible in 2140 hybrid
