I'm actually in the same boat as you; have about 600 jumps and will be coming back to skydiving after a 3 year layoff. From what I've read, sounds like most places will just have you do a coach jump and maybe even have you sit through FJC. Guess I'll find out in January, but I'll also have 4-5 hours of tunnel time by then (started racking up the tunnel time a couple months ago) ;-)
