I met Tom at the NHC in Grand Rapids - his talk was on everything about beer dispensing from kegs, line balancing, etc...quite informative. It sounded like his brewery was taking up a lot of time, together with his academic pursuits kept him very busy.
Great guy. My takeaway was to change your beer lines periodically, run your beer cleaner backward in the lines, and start with a longish dispense line and trim until the beer foams to the desired level. (And buy the beer line in bulk!)
