We're currently working on a drivetrain based around 15mm wide 5mm GT2 belts, and 20T pulleys. The gates website has a lot of information regarding the rated load capacity of different profiles/belt/pulley combinations, and it looks like 20T pulleys should be sufficient, but some real world experience would be helpful.
Having a number of teeth that is evenly divisible by 3 lets you hold a pulley with a standard 3-jaw chuck more easily, just in case you want to do something to the bore.
