Good Morning, Joe,
I normally rate T-100 at approximately its box speed, for both LF and smaller sizes. T-Max developer (1:7 from the concentrate) is my usual choice, but I've also had excellent results from HC-110B. My "normal" development time is 10 minutes in T-Max 1:7.
One other thing to note is that T-100 has extremely favorable reciprocity characteristics, making it ideal for night shots. For those I favor Technidol (about 12 minutes with 10--not 8--ounces of solution from the developer packet); due to the cost of Technidol, I'm also experimenting with very dilute HC-110 and stand development for night shots, but haven't really zeroed in on time yet.
