perf pro. also there is MaxTrainer which is very inexpensive, but the interface is unique (you probably either love it or hate it)

x2. PerfPRO Studio is the hands-down favorite for multiple-trainer situations. Been using it since it was being developed, and it just gets better and better. Stable, uses few resources, runs almost any trainer (smart or not), and Drew is always open to suggestions. My advice is, buy it before it goes to subscription (like [it seems] everything else)...

Go the Perfpro set up too. We use this for our sessions with 10 to 15 trainers, most with ANT+ sensors for HR and/or virtual power.
