The weight argument is mostly pointless for any UCI race. If you're serious, you can get a bike with virtually any non-disc rim under the weight limit. So the weight penalty is zero.
Rotating mass still matters, but it really depends on the acceleration/deceleration profile of the race. If you're braking into every corner and accelerating out, it'll matter a lot more than a sustained climb.
