I've grown all 3 strains mentioned, and for all 3, open them up as much as as possible. SCROG, LST, top, fim, supercrop, whatever..... That and lots of space, especially for the Ultimate.
All 3 is heavy yielders, but I don't see the FD and CC as 1 pound candidates, even if I had a FD yielding 240+g dry grown au naturel. The 3 CC's I have going will come down in a couple of weeks, but I doubt they'll give much more than a 100 g or so, hopefully I'm on the low side..... We'll see!
For that 1 pound, or even 1 kg which has apparently been achieved, Pop's grow method with an Ultimate would be my bet, with aggressive training and removal of in-the-way leaves(I have no experience with DWC but think it would be a walk in the park if done correctly) and all aerial attacks thwarted, of course......
