Dr Greenthumb's Endless Sky would be good, very potent and good yielder. Short, little stretch, 42 days flower.
I grow his
Big Laughing - short and high yielding but branchy. I use tomato cages to hold up the branches, heavy dense nuges. If I veg to 16" (single cola, soilless) I get a 24" plant every time (2100K HPS); a plant that size takes up a foot in diameter. Thick cola like a cone with a wide base, like a witch's hat. 2+ oz per plant off a 2' plant, every time. Been growing at least one plant per grow for over two years. In DWC the colas are more dense, slightly smaller but weight more, and more crusty with trichs. In soilless the colas are spongy, a solid mass.
I'd go with
Endless Sky if you wanted an indica stone. I'd take a look at
Jazz for an up high, a bit more potent than
Big Laughing. Jazz is going to give you more stretch, you might only veg to 6".

I'm growing
DJ Short's
Flo for the first time and have a clone in RDWC. It's grown from 6" to 22" with a couple left to go. The interesting thing about Flo is there is virtually no lower branching like in most plants, A forest of Flo should produce good buds right to the bottom of the plant. I don't know what the yield will be like.
