I've never raced on a circle track before, and decided to try out the EcoStocks this year. I've been road course racing for the last 10 years. I've never been paid a single dollar for a win, place, or show, let alone getting my entry fee back, which can be several hundred for a sprint race weekend to $1650 for a 14-hour endurance race on the Daytona road course. So I was pleased as punch to get $100 for taking 3rd place at the last race.
I've got to say, though, the biggest difference I see between what I've been doing the last 10 years and the circle track is the animosity towards the track/promoters/officials, both at the track and on the web. Nick and others have been preaching it for years, but the racers seem to be their own worst enemy. If we want to have a place to race, we all have to realize that it's a partnership between the track, the promoter, and the racers.
And yes, I only race Ecostock. You probably spend more on tires than I spent on my car. Well, so did I. It's just that my tires will last a little longer...
