lighest wheels or most aero wheels?

In a circuit race with mostly long straights, what wheelset would be optimal?

IE: a lighter wheel such as ksyrium sl's OR anything with an aero section like a Cosmic or a zip 404/303 ?

I think I'm going to use the search function and search the racing subforum to find out if there's any other threads on this groundbreaking topic.

I think ksyrium sl's are heavier than 303/404, tubies and clinchers (tubies are definitely lighter).

Unless it's a pure hill climb, or a race that ends with a big hill and you're going to be protected by teammates until the final climb, aerodynamics always trumps weight.

Is there a point where the coefficient of rim depth/weight negates this statement?

IOW, would a 40mm rim depth but 3kg wheel weight negate this statement? especially in a crit, where accelerations are frequent?

I'm sure one could be made.

This set is over 2kg: http://www.flash-pointracing.com/fp80

I think the soul 4.0's are a pretty good balance between cost, weight, and aerodynamics. I forget who, but someone came up with the number that 40mm is right around where the 'real' benefits start happening.

Was it fatboy? Some engineering types, I don't even remember.

$420 shipped is nothing.

There is a crossover point for depth/weight which is partly why you don't see any 80mm deep all aluminum rims. It is a pretty complex calculation to figure out where the crossover is and you would need to know how much time you spend in the draft of the pack, and how much you slow and accelerate for each corner and a bunch of other factors. Maybe Waterrockets is smart enough and geeky enough to do the math.

Waterrockets solved this question for us months ago.

Who wants to dig that one up?
