agreed on the UNI's in general...tho I only hated installing the original non-stretch nylon versions. the later lycra style didn't require you to pop the freewheel off.
with a moderately deep section rim and CH-Aero's you just need tape (like someone else already said) and voila the interface at the rim is really no different than a disk.
as for the hills at IM-W (a course I've ridden in training but not on raceday) I seriously doubt that there's all that much rider-caused acceleration going on. what does Slowman preach? constant power output...shifting as needed for climate and terrain, but keeping that wattage steady, right? are you trying to tell me that at the top of a climb you're going to actually stomp on the pedals (i.e. accelerate) into the following downhill rather than letting gravity do the work for you? you're going to stomp on the pedals out of every turn like the crit maniacs? those kinds of accelerations are where it makes a difference. besides, even if you DO do that, you're accelerating a system (bike + rider), not just a wheel. the former takes a lot of effort...the latter is a very very small part of it, and the difference between two disc wheel weights is very very much smaller even than that. acceleration is not the player everyone thinks it is, and especially not on a component by component basis.
1-2 min for disk weight deltas in an IM, eh? Whether that's just for the bike, or for cumulative effects (bike split plus run deltas brought on by excess or lack of energy attributable to disk weight deltas) I'm guessing that the well-documented Murphy's Law effects for all the other race variables make that 1-2min almost meaningless. How many other things can cause a difference of 1-2min...or more?
