I've just loaded my first roll of Kodak T MAX 100 in to the camera. I use Ilford chemicals, ID-11, Ilfostop, Rapid Fixer, I've just started to look at developing and fixing times online, I'd really welcome comments from anyone else thats used this combination of film and chemicals.
Just go for it, i had that bug before, but once i started i never look back, i lost few rolls because of mistakes [wrong loading, not exposing the roll], but the development was always or mostly spot on, if there is a problem it is mostly me, follow that sheet Ian linked to and give it a try, Ilfostop and fixer are not a big deal, just let us know what you will get.
Just souped these TMAX 100 in ID11 (1+3) at Ilford recommended times at around 69F/70F. I think it was 14 minutes, but will have to check. Link to my blog (it's safe):
I used to do two bath fix on Tmax as well, but I stopped after awhile. Seems like it didnt need it, but what it did need was extra washing to get the dye out.
The advantage of 2 fixing baths is that often when using a single bath that single bath becomes silver saturated and does not fix properly. Leaving you not knowing at what point that fixer became exhausted and if the film has been fixed sufficiently. So I always use two baths and test the first bath while the film is in the second bath, when I discover it's exhausted, I simply extend the fix time of the second bath by a minute.
