Had I already had my aero helmet for the state TT championship this year (yeah Raven, I don't have mine yet either , but Giro FINALLY is shipping them, so I should have it soon!) I wouldn't have won, but I may have been able to move up, up to 2 places and I would have medaled! I was less than 3 minutes behind both 2nd and 3rd places. Not to mention that in some of the stage races that I do the overall placing are done by total time, so while I may not be aiming to win the TT, I would want to lose as little time as possible.
No an aero helmet isn't something your everday rider will want to wear, they are hot, heavy and aren't effective unless you are riding in an aero position, but if you TT or do tri's they are one of the pieces of equipment you will want to consider.
