Aside from not being recommended by Kodak, no reason at all. As others have posted, try it. It may be just fine for you. Me, I just don't use TMax developer. When I was starting out I used all kinds of different developers, and I can to the conclusion that I could get by with just a few. I've been using D-76, premixed A-B Pyro from Photographer's Formulary, Xtol, and Ilfosol-S. Acutally, that's probably too many developers. But usually I use Pyro or Xtol.

+1. Just do some test shots, and see where the sweet spot for your lens happens to be. After I aligned my Super Graphic, I found that the 135mm Wollensak Optar lens gave me bicycle spokes two blocks away.
