There are alot of good grasses that will work for your area. Orchardgrass, Timothy, and Bluegrass will work. Heavy stocking and rotational grazing should take care of the broomsedge issue. I'm not a big fan of fescue, but I'll use it when it's there. I just don't see a point in planting any. If you don't have any, you probably will eventually. If I did any seeding, I would be overseeding with legumes. Frost seeding of clovers and other legumes will make any pasture better.
