FWIW, I've finally got my conventional wheelset in hand.
The tale of the scale is 1,950 grams for the set, noting that the rear hub has an integrated disc mount. So, for a more accurate comparison you must add the 62 gram thread-on disc adapter's weight to the low-spoke count racing wheels which gives you a comparison weight of 1,862 grams (yes, for some reason my the low-spoke count racing wheels are reading 30 grams lower than spec, and i don't believe the decals that I removed could weight that much) using the same Ultimate Alpine scale. That's a difference of 88 grams... and if they'd used the correct spokes that difference would have been 18 grams.
Now, for an apples-to-apples comparison, a White Ind. Daisy rear hub (left-hand threaded just like the low-spoke count racing wheels) would need to be spec'd, and you'd lower the weight of the rear wheel by 78 grams, which would better the weight of the low-spoke count racing wheel's by about 60 grams.
Again, the Fusion rim is not one that I'd recommend for heavier teams that need a wider tire (28mm and up), and I personally prefer the Deep-V even though each rim is about 20% heavier than the Fusion. However, for teams who can get away with running 23mm or 25mm tires, it demonstrates that you can build up a conventional wheelset with 36° hubs/rims and a semi-deep section / aero rim to achieve a wheelset weight of about 1,760 grams.
Tomorrow we'll see how they ride compared to the low-spoke count racing wheels.
