Don...... I’ve only ever raced with Bell full face helmets (Usually a “Sport”), since 1970. Last year I was trolling around EBay and spotted ZAMP Helmets. They were priced so decently, I just ordered one. Terrific, fits me perfectly, and very light! This year, the little serrated washer that holds the visor open snapped. Contacted their service dept. and a very pleasant person sent me a new one immediately (small charge for shipping, part was free). It fits, I’m pleased. Check them out!
