The Contenders:
1) Giro Synthe (non MIPS - priced for $150)
2) LG Course ($160)
3) Kask Mojito ($165)
4) Kask Vertigo ($125)

I've tried them all, and all of them feel good and fit. I live in hot and humid conditions with mild "winters," so ventilation is the most important and aero is just a plus.

Feedback, input, and opinions/experiences are greatly appreciated!
