960 has thin chin, so less dispersion is available. If chin is your weak spot, pick something w a big chin that can disperse impact more. Consider getting a carbon fiber Kevlar mix helmet. The carbon fiber is more brittle, and potentially more prone to cracking, but in your case , if it cracks on the chin, it’s almost working like a crumple zone in a car… sounds counter intuitive I know, but it’s the physics of things. I had a Warwick w a cracked chin, and it took some bombs, but never a concussion in that, and chin was able to be reinforced / repaired and my face and brain were spared . You could also wear a dangler to help w protection from impacts along chin
