Replying to Electric EG2 Lenses?

Ok guys, I went ahead and bought some EG2 (they are sick as all get-out, BTW), but now I'm thinking I might want a mid to low-light lens (think Pink Iridium, or perhaps H.I. Yellow) for them instead of the one it came with, cause it's almost like a Fire Iridium, and looks to be best for really bright days, and I don't get many of those.

So who's got the low-down on Electric and the tints they have, the light transmission, and where I can buy extras...I looked on their site, but have nothing to show for it, am I blind?
