I love all of my combo's: Black shorty diamond series with the purple LED with purple cart and purple drip tip, Black shorty with red LED with red cart and red drip tip or with brown cart with black delrin drip tip, Chrome/Platinum shorty with blue LED with black cart and silver drip tip, and Chrome/Platinum shorty with green LED with light green smilin cart and green drip tip. I mostly use red, purple, black, or brown carts and only black or chrome/platinum batteries. I'd like to see the black diamond series battery with a clear/white LED and a red LED and I'd like to see a Platinum/Chrome diamond series battery with a clear/white LED or a black LED. I think a black LED would be phenomenal on any color battery! That is if a black LED is possible (like maybe a black/grey gem with the clear/white LED behind it).
