On my 2nd Nolan flip front - yes they are heavier & generally noisier than fixed full face, but the convienience element of a flip front is worth it IMHO

Dont know what they cost nowadays, what with Blue tooth thingymajigs attached and all that stuff, but I picked my last one up for £125 3 years ago as it had been replaced by a newer model.
Just my ramblings . . . . .
