I've found that Fuji SPD developer results in much less grain than D-76 when using Tri-X 400. D-76 requires more vigorous agitation to avoid uneven development but that results in more grain. SPD works great with very slow agitation (continuous for first 60 seconds followed by 10 seconds each additional minute). Speed of agitation is about 4 full inversions in 10 seconds. With D-76 I find that I have to do much faster and more frequent agitation for about 4-5 seconds every 30 seconds or else the edges get bright and center is dark. I've just purchased a bunch of T-Max 400 and a bottle of Ifosol 3 so we will see how that turns out in a few days.
