Hi Shawn (510 parts and carts)

[towardsthelight]

I actually have a titanium(silver) yeti(510-sometimes I guess called a cylon) with a red led, but I also have a few silver batteries with the blue led. I have the silver atty's. However, I mix and match, my girlfriend has a black with green led, and she likes all the led colors(blue, purple, red, green). So sometimes I'll use a silver battery with a black atty or vice versa. It would be nice if you had a few silver(titanium) batteries and atty's to choose from. But that's up to you. My friends and coworkers all have the black with either the blue or green leds. I don't think I've EVER seen a white 510 except in pictures.
I always use the black carts(of course). I exclusively use the manual batteries. I've heard from everyone that manual batteries are superior in almost every way. I bought a cheap(non-510) auto battery kit once(off amazon) and the cut off sucked,also it failed less then it worked so I sent it back.
So I guess the answer to your question, for me, would be Black or Silver batteries and atty's (with pretty much any color led's) and black carts.

Yes, yes, Cylon silver!!! No preference on the LED's
