What do you think about...
4 blue +
2 aqua blue
2 figi
I'd get 5-6 blue + and 2 each of the others and experiement a little. That would mean a couple of extra bulbs, but that's just a couple less bulbs to buy when replacement time comes.
Blue + really are nice bulbs. The figis are kind of weak and IMO it's hard to say what they really do
