Scott, the way I have it configured in my head now is as follows:

The bikes are already legal (and probably competitive in Colo Class).

If we ran them as a "two race per weekend series" for an overall weekend championship then there's two more...

Three classes that you KNOW you'll be competitive in should suffice for value of racing oppty vs. purchase cost of the bike.

"IF" the grid grows to the point that it deserves to run by itself, then we look at that - but I'm reluctant to throw another class out there that might only have 6-8 bikes to start.

Honestly I don't see the bikes being competitive in the current lightweight classes - but I guess people "could" race up if they wanted to...
