Good Evening, Todd,

My usual combination is T-100 developed in T-Max. The developer works great with both expansion and contraction--at least up to around plus or minus 50% of the "normal" time. In general, T-100 is very responsive to variations in development time. I've also used the same developer with T-400 and had excellent results, but usually at the "normal" time. Experiment! I think you'll find the T-Max developer to be very versatile.
