road wheels - bladed spokes?

[kona kid]

I'm after some nice light road wheels to replace my R550, so was quite keen on the DT Swiss RR1450 - but they do a nice bling set with white rims, black revolution spokes and red nipples OR a balck/silver set with aero spokes. Obviously the black/red/white set is much cooler looking, but not aero

i can't believe that aero spokes make that much difference, seems more fashion that anything, will I regret the regular spoke choice?

if it makes any difference I typically cycle at ave. 30km/h (but bench about 500lbs )

at longer distances with equal speed aerodynamics are more important than weigt. best is a combi of both offcourse.
