I never had a problem with the Ben 2. Sure its not with tradition as a leather is but it out performs the leathers in with its main feature......safety. Not all Ben 2's have the rubber bumper, I have 2 Bens, one with, one without....go without, otherwise you'll just end up ripping it off anyway. The main grip I do have with the Ben is that the frontpiece holder will snag and you'll lose your lid if its not strapped on, but a fix can be added to keep that from happening. Its lighter, more comfortable then the new leathers, and will protect your head from impacts better. You will also not have to spend money to refurb it. Outside of work, the Ben 2 I have is 15 years old and been through a ringer and its holding up well. I have only needed to replace the eyeshields twice, thats all.
Cairns 1010 is a shoddy made plastic helemet. If you drop it and over time it will develop chips on the outershell...the helmet's integrity is compromised and is no longer good. They also tend to melt to high heat.
The best leather ever made was the original N5A is not like the leathers of today. The old ones were and art form....custom fitted, hand made....the best. Not so much today.....
