Very many thanks for your input, Bill. You have a good looking, functional lid. I'm pretty sure I'll be getting similar (perhaps the same) once I can try a few on. I must say, in 34 years of biking, I've never had an open face and am really looking forward to experiencing the unrestricted element they undoubtedly offer.
I've been hinting one might be warmly received this valentine's, but have so far been met with, "That's not a romantic gift." Got my thinking cap on and some work to do!
