I have a roll of T-max 2300 (135) that I want to process. I have exposed this at 1600ASA and I have some Paterson Acutol - it doesn't give a development time for this film on the label, but I was hoping to use it anyway. It gives a time of 11 mins for Tmax 400.
The consensus of suggestions that I got was to shoot it at 1600 and develop it (in whatever developer) at the time for 3200. I've got decent negs. In fact, I was going to print some tonight.
