I have a 6'1" Yamaha C3 in a bad room. I usually mic it with a Wunder Audio CM7 GT(M7) and a Telefunken AK 47 through a pair of LA 610's. I put the lid on the big stick and cover it with a blanket to keep the room out. After a fresh tuning, this works to great effect. I have used many sample pianos but nothing is even close to the real thing. The dynamic range alone is vastly greater than any sample.
