Yes, Patrick, I've been re-reading the Marine Plant book a lot lately! I like several of the caulerpas, but I may avoid them this time around, to avoid the heavy pruning duty.
For the back wall, I am considering Maiden's Hair. It loves bright light, spreads out, and looks good in the current.
I agree on adaptability. My C. racemosa peltata likes shady areas, but it grew right up to the surface and pretty much everywhere else, at its peak. I'd still like to grow botryocladia at the right end of the tank, in dimmer light. I still have a few tiny remnants, but I doubt they'll survive the re-do. Another red I'd like to have is Dragon's Tongue. It too can grow pretty big. I tried one of the eBay frags, but it didn't make it.
My theory on macro frags is that they're too small - almost like a short fuse. I think you need a bigger plant to give it more time to adapt to your conditions and/or time for you to make changes to suit it. A smaller plant gives you less time for that to happen.
