hmm intresting, Trials doesn't have the money or sponsorship backing to pull something like that off I don't think. Theres probably only around 4-5 riders in the whole world who could make a living riding just comps to be honest and that is risky, one injury and your screwed. Very few riders are on full time wages from a sponsor to. Therefore other riders must do demonstrations etc just to make their living, they are less likely to push themselves and get injured as again it means lost money. The window for making money is small as well with most riders making their money in the summer. unfortunately it comes down to money in all cases I think. Although it would be cool to see, I think it would be difficult to get the top riders in the world to commit without the cash. Mark as for comp riding surely you do the most efficient/ suitable way of doing something? which means that people will probably do things in th same way? Although i'm sure if you watch some of the top riders more closely you'll see massive differences in the way that they do things.
