Well done, riding almost 40 years...
I am leaning on 60, and just bought my first full face, an R-1100... You use the vents, I run with sunglasses and shield up except in the rain... You will get used to it. If anything, now it gives me a snug home feeling, snug fit against my jaw, and becomes one with my head.
Mine is black, here in summer in Australia gets over 100 degrees, and not a drama. If anything, you gain a little flexibility as the only action is to "Head Check" you gain that look over your shoulder extension and it seems to improve your stretch. It is the only F/F that fit so well. You did the smart thing there, not an extreme, a very good move. Congratulations...
From the Pros stand, Shoei is near or at Number One in the world... I am going to look at the new HD F/F that is talked about in the F/F topic, for better Blue Tooth and communications if it is set up for it for my new CVO 11.5 BIG BLUE coming in July to Oz.. But you have done a very good thing there.
If you break a leg, there is always a Trike.
Breaking your head, ends joy on a bike...
