Just a comment regarding running a GTL race on a sunday eve (when available).
No-grip run a GTL race every sunday and it has 30+ drivers attending every week. I think if you advertised a sunday race/league on sites like theirs and RSC then you would see similar interest levels. GTL has kind of become more cult like now with a central core of racers who really want to race classic cars as opposed to the fly by night racers who just race whatevers there. Thats why the racing has got better, even in our (your) own ladder league. Its attracting the enthusiasts.
I am also sad to see Rf not that well supported. I had only today posted on our legends team site that everytime i thought i would buy it, i would suddenly see posts saying how bad the attendance was for the races, and that put me off each time. I would love some full grid single seater racing to compliment our tin-top stuff.
Anyway, just my pennies worth.
