Hey all. I'm posting here instead of over at the Tri forum, as I think I'll get better opinions here. I'm in the market for a new helmet, specifically for Tri racing. That means aero. But I don't want a dedicated TT helmet. I want an aero roadie. My search essentially brought me to the Specialized Evade. That helmet seems to be the standard of road aero helmets, or at least in the top 3. But I rode today with my Bell Formula Mips, which was $50 beans, has a 5-star rating from VT, and fits so well that I don't even know I have it on. Keeps my head really cool in the desert heat. So I got to thinking: do I even need a new "aero" helmet? Will it make that much of a big diff in an Olympic Tri (which I aspire to)? And if so, what of the Bell Z20 Aero Mips? So less expensive, and I already like the brand. Any opinions on that model?

Thanks all!
