For 1600speed B&W, I have had good results with Tmax400 pushed. Other people get good results with Tri-X pushed. I mostly make prints in the darkroom, but have no problem scanning Tmax400 with my Epson v700. Don't use Tri-X but imagine it should also scan well.
Keep it up! At my wedding 10 years ago, I had one photographer shoot the normal color stuff and groups, and had a second photographer shooting B&W film (tmax 400 pushed) only which I processed myself.
