Yes, we did have very similar experiences...our heads must be similarly shaped. My Arai dealer advised me that most of the weight of the helmet comes from the internal padding, visor, etc. So the actual difference in weight between the GP-6S vs. GP-6 vs. GP-6 RC isn't that much, but he didn't give actual weights. Plus the Carbon helmet has to meet the stricter FIA standard for F1, so that adds to the weight of the helmet.
Any tips on how to install the chatterbox radio?
