My experience is limited, but I've had success with Perrienal Rye. It starts fast, grows to some 12" then sorta lays over. Deep rooted Bermuda would be best to get started next summer. Centipede grass probably would be great in AR, but stresses during cold snaps further north. I'm interested in 'Thermal Blue.' Actually, it has more fescue in the blend, than bluegrass. It seems pretty popular in all the Lowe's and Home Depots I've been in. Supposedly, it has an improved Kentucky 31 fescue (which I've used and like), some short fescue, and the thermal blue, heat & drought tolerant bluegrass. Sounds good on paper. The P. rye and fescues tend to tolerate partial shade. Best to 'ya.
