I really thought that would start a flame war. Since it didn't, I'll say that I've found Sunriders courses to be a lot of fun. Although they are not as fast as Sebring/Lakeland/FSF they do have a few things that the SCCA sites don't. namely the SPJC pad is almost clean enough to eat off of - virtually no marbles. Secondly, the courses include elements such as sweepers and decreasing radius corners that I haven't seen (so far) in the up and back nature of FSF/Lakeland/Sebring which lends itself more to sloloms and offset gates. I think it's helpful to see some of those other elements.
