Go here to retrieve Kodak's publication P-255 on Tech Pan. In it you will find a chart with various developers and their contrast indeces. CI's range from 0.5 to 2.5 so you should find one that is as contrasty as you want. I have used D76, Tmax, D19, and technidol on Tech Pan and they all had very fine grain. In fact I think that it would be tough to produce a negative with large grain.(posted 9169 days ago)
