Kregan:
I have an E-Flite 160 om my Blackmagic V2.2. It was an YS conversion to electric. So far, I have no regrets on the conversion and am completely satisfied with the 160. I am usin a CC HV110, 20x10 prop more than sufficient powr. Verticals are long and consistant. I was using a 20x13 prop, but plane was much too fast and difficult to throttle manage. I'll have to try it again and see if I can get use to it.
I would however, in your case consider a CC HV 120 or the ice 120. when you go to the larger props, you'll be pulling more amps, perhaps pushing the limits of the ESC.

My $.02 worth.
