I see a huge varried mix. I couldn't even say one dominates the other. Anywhere from12 year old on bighit groms to 67 year olds wearing a full face and riding a 2002 RM pipeline.
All of them offer something different. Younger offer a balls to wall riding style that precedes adulthood. The old guy offers 40 years of riding and endurance that is unheard of. In between is everything you can imagine from pros to hacks.
