Question for John Cobb re helmets

John,
At FISTapalooze you mentioned that different helmets suit different shaped riders better or worse.
If I recall, you said that the LG Rocket was better for those of us with rounded shoulders and rounded backs.
I can’t recall what shapes were better for other shapes and thought that might be useful to post those, or to write an article for Dan or for your website. If you have already done so, please excuse this post.

BTW, do you find the the Rocket Air loses any significant aerodynamic efficiency than the older Rocket with the smaller vents?

Bump. I’m interested in this, too.

While he didn’t name names here, it gives the explanation. And A back riders would look for a long tailed helmet (Spiuk)
