I have both and would definitely go with the HEDs. I have a set for training wheels built up 32 spoke on CK hubs. They survived Flanders and Roubaix without a hiccough under my 200+lb corpulent ass. They are more comfortable than my tubulars with Michelin 25C tires and plain old butyl tubes.
Out of interest what sort of frame were riding and what were the clearances like?
I was running the Michelin Pro 4 Endurance 23C on my HEDs, but switched to the Michelin Optima Pro which is a 25c. They are HUGE on my current bike (old custom steel frame) and the clearances on my new bike (Baum with Enve fork) is quite tight.
As much as I love the plush ride (especially on coarse asphalt) I think if I bust a spoke I'd be stranded (which kind of defeats the purpose of building a 32-spoke rear wheel). The rubber mold 'needles' on the side of the carcass touch the chainstays.
