BD, As far as my road bikes go I have a 28H wheelset (D-A hubs, 15-14 DB spokes and Open Pro rims) that're not exceptionally strong, but has lasted a few Ks of miles and yes I spec'd that wheelset simply for appearance. I don't take them out on century rides as the 'distance' bike has a much stronger 32H wheelset (Ultegra hubs, 15-14 DB spokes and CXP12 rims)... I don't want to even think about my wheels on a ride, much less worry about them as I ride solo most of the time.
I think the ultra low spoke count wheels are probably fine for rides where there is SAG support or a team car, but from a common sense stand point you've a very good wheelset.

PS Are 28H wheels even considered "low spoke count wheels" now-a-days?
