When should I go to better camps

[Junker]

Ok this is aimed at you DIII, DII and DI college guys. When should I get serious and go to a big time college camp? I've been working for 7 seasons, I work 4A high school ball (the biggest in my area) and just finished my first season of JUCO women's ball. I know I need some more "seasoning" before I'm ready to move up or have a shot at moving up, but age is going to become in issue I think. I'm 35 now. My question is am I better off starting to go to those bigger (and more expensive) camps now, or wait a few seasons until I'll be a better official. This isn't a pressing issue but I'd like to hear your thoughts.
