Its great to read how well OG Larry turned out, you'll have to give us a smoke report after she's done curing You've really grown some different strains there and I always find it interesting to see which ones suit different people and why.
I'm trying to decide a similar thing too at the moment. I love my Kandahar but there's 2 distinct phenotypes - tall and leggy or short and stocky - and its a matter of which one to carry on with that suits our grow space (both smoke great).
Are you able to post up some pics of your flower room upgrade? I'm curious to see how much difference adding the T5's will make, its not something I've done yet and its always interesting to see if its worthwhile trying.
