Heh I normally run 6 (2x Dinotte 140L, 3x PB Superflash, 1x Viewpoint Flashpoint)...I've some others laying around that I could strap on, but they're just regular 5 LED blinkies and I don't think they'd add enough to be worth the extra hassle of turning off/on and worrying about more batteries. I think I've got you beat on total light output
