Even with Sharc's perspective in mind, the basic +50 Crowd is not full out MX riders anymore.... and the idea of racing on a track that has "big" jumps with some other guys that "Jump" those big jumps will have an effect on +50 riders coming out that have not otherwise experienced BC before anyway. Anyone that is in that class that has never been there before and has hesitation to come..... won't come. They would like to come to BC and see it first before racing there if they are on the fence for sure..... it's a sure bet to have 2 strokes with a lot of riders in there, whether they are there or not already, it's money in the promoters pocket!
And depending on classes you do plan on having..... +40C class with no tripling rule would be a good alternative to a +50 class for older slow guys from 40 on who want to ride there but not get jumped on. That gives a lot of people a chance to ride an old / slow / non jumping class....... in my opinion.
Being 50 now, part of what you say is true. As long as the jumps aren't ramps that can't be rolled or jumped with a fairly nice landing, then most of us older guys wouldn't like it. I've been to Beans and the jumps there are good. Actually a great improvement from the last time I was there. I don't think in a 50+ class that anyone would have to worry about getting landed on.
If I can get my self in shape, I would definitely come down and try it out.
Let's hope you get more responses from the 50+ guys.
