Aero helmets

Hi everyone, I am currently in the market to purchase a new aero helmet for my road bike, I don't do alot of racing on my road bike as I'm a time trialist however I fancy a bit of bling and therefore can't decide on the following either a Kask infinite, the specilized evade, the poc octal (not the aero one) or the MET rivale.
I really like all these helmets however was wondering about your opinions on fit, ventilation, and just looks as well as performance such as weight.
Any replies appreciated
thanks.

If you're not aiming to race on the road bike, you might as well go for a well vented helmet like the Giro atmos, as you'll probably prefer the cooling effects more often than aero. Especially when you're training for your time trials.
Got nothing scientific, but its definately much quieter than my other lids.
Might be worth trying to get your head into the candidates to see what feels good.
I'm sure any of them will feel beautiful, compared to whatever TT race lid you wear.
