According to 'wobbling.unicyclist.com' (http://wobbling.unicyclist.com) Profile hubs are 565g and Suzues are 370g. Profile cranks are 588g per pair (not sure which length was measured).
Do you know how much the UDC hub weighs? I forgot to weigh it before sticking it on my Coker

"Give man dead fish, and he feed himself for lunch, teach man to catch fish, and he feed himself for life. Teach man to wheel ride, and he make friends everywhere, anywhere, and even have lunch at their place." Old Chinese saying
The Qu-ax hub WITH 145 mm cranks weighs 1400 grams or 3.06 lbs. Try going directly to Municycle.com and ask via email what the hub, alone weighs. I would also call unicycle.com and ask them to throw a KH hub on a scale for you.
