My view is that it can be both.

I do not think that there has to be a class for every variation of cobra or to take into account all of the variables that may (broadly speaking) influence lap times.

I am, as I have said before, in favour of broad classes for the ShelbyFest.

eg.
5.0L (stockers - say factory (or not very big) cams + road tyres)
There are heaps of guys with a nice car that gets a once or twice yearly track day and ought to be able to give it a go with some prospect of placing well.
6.0L (anything you like except slicks)
Starting to get serious and has the potential to produce the quickest lap of the day
6.0+ (racers - includes turbo/supercharged motors - anything goes)
The loonies who are too far gone and should be segregated for the general health of society.

On the basis that if people spend the $ they get the benefit and the variations make classes somewhat arbitary anyway.

That should leave room for the more imaginative 'personal best' type events.

I really enjoyed the regularity aspect last year, particularly as I thought it let everyone in. If it were up to me I'd make it the 'Perfect 10' event - where you are ranked on the time difference from your fastest and 10th fastest lap.
I think its much better to take a good segment of someone's day and let people push a bit (and possibly make mistakes and recover).

My last thought is that if people want to have comms/timers why not let them?
