Well your indoor ones look like you're doing an alright job ... if you're going to LST, I'd do it now ... and, I WOULD definitely LST. It's a good idea, especially when using CFL's. You've got basically the same setup going as I do, with that many lights. My nodes are all clusterfucked like that too. It doesn't seem to be a bad thing, and when you tie it down, those things turn into main-node's, seemingly. Keep doing what you're doing!
