An old man's perspective
The idea of mixing intermediate and expert on a team seems appealing. I have no visions of grandeur in winning, either at my age or my bikes age. I stopped competing in the endurance race because it was a forgone conclusion that Ian and anyone with him who could lap sub 1:03 would win. Not too many bikes explode these days.
What this means beyond Ian, Pete, Jason, Justin etc. being phenomenal racers, I don't know. Put Ian and Pete deGraff on a single team on a liter bike...and for me the fun goes out of racing, unless you enjoy counting the number of times they are going to lap any other team. Don't get me wrong, I'm happy for these aces to practice their hobby...but not at my literal expense. Perhaps bike classes would deal with part of this issue.
Would eliminating payouts and dropping entry fees help? I suspect it would. We would then see if the local superstars have the same motivation as us "also rans" who make up the majority of every grid, in getting out "for the love of racing" and for having some fun with their racing buddies. As it stands under the old formula, it just seemed that the less talented riders like me, were only there to pay for the winners to walk away with a profit...along with maybe 25-30 more laps of racing than my team.
I'd come back under a more equitable cost structure that eliminated cash prizes. A new formula that perhaps offered some other incentives for the superstars to compete for, that weren't directly paid for by my entry fee. 2-3 Bike classes would make it more appealing still, and some sort of age allowance or calculation would enhance a team's chances even more. Add the age of the riders and their bike, along with handicaps for expert vs. intermediate, for some kind of overall placement formula.
Just some thoughts for consideration.
