Yeah, I had the same mindset about Fundies probably being my last class from GUE as well. It actually did turn out that way, but I did think long and hard about doing Dave 1 through them.
Also, a note about the people who might sit in on a fundies class to help video, etc. Don't think too highly of them. They might make it look easy, but they are not in the same situation as you are. Its a lot less stressful being able to watch from the wings than it is to be under the gun doing skills. Its easy to look over your shoulder and see them hovering nicely in trim, but you are only looking at them once every 5 minutes, so you just don't see it when they back up into the wall or come up 3' by accident. Plus they already have the benefit of having been through fundies, and working on their weaknesses for the last however many months/years.
I had the chance to sit in on one of Ed's fundies classes a couple years ago, and I did video. I don't think I was all that much more stable in the water than the rest of the divers, but I think I was seen that way. Since then, I've been in the water with all three students a dozen or so times, and have done tech dives with them in the Lakes. I really enjoy diving with them. Anyway, my point is, if someone is tagging along with your fundies class, think of them as a future dive buddy.
