I'm casting around for regular open-wheel racing at the moment. To be honest I was hoping for some lower-powered formula stuff but I'm certainly not averse to some top-level stuff. Besides, I just signed up to a big wedge of iRacing and am getting a good fix over there. I'm not, however, a top-speed driver; I won't be challenging for wins. But I'm very experienced [read: safe] - mainly endurance racing, and if I sign up to something, I do attend.
The twin-race format sounds interesting and fun so, with your permission, I'll monitor this thread, do any practice/fun races, and try and make a nice early call on whether I'm in.
