(yes, I have way too much time on my hands, but as I sit here typing, I look at the "red" Titan I'm vaping right now, with the surprisingly pretty red and black swirl drip tip (the only red that works w/Titan red), the light green tank, the dark juice, and it just really pleases me no end. It's like a piece of jewelry to me -- art, even.
But there's little else for the other colors, especially when you factor in tank color. The options for lavender and blue are close... yellow is okay, so is grey, but olive, cigar, pink, green, and worst sapphire are pretty hopeless.
I wish Vapor4Life would expand its inventory to put together multiple great looks for the Titans.
Re LED's, I think I'll start a seperate thread
