I don't know what chemicals you have on hand, but I have had much success with Delta 3200 (135) stand developed in Pyrocat HD. You get very sharp negatives with a nice amount of grain. I've only enlarged up to 5x7 with it, so beyond that I don't know how the grain looks. I've tried delta 3200 in in T-max Dev, but it didn't give me the contrast that I was looking for. Good luck in whatever you choose!
