Go to the Va Tech site, buy one of the top rated ones. You have gotten your money's worth out of what you have. There is little question current helmets with MIPS etc are safer and you don't need to be going 60 mph to destroy your brain.
Why the lecture ? I've gotten wacked in the head hard enough to be knocked out 3 times: once soccer (no helmet) once motocross ( helmet), once skiing (helmet) . The last left me with a concussion that lasted for months...it was really scary (ski helmets are mostly garbage) Helmets are not a fashion statement. It won't look cool at all when you can no longer think
