THAT is PRETTYYYY
Then the SS version and the Cu version would match, with copper for the light engine all the way around… a necessity for the FET driver. 
That would be incredible! We will ask!
Perhaps the cost difference could be mostly balanced out by having the smaller K6 also in SS with the Cu finned light engine area. This would use less copper for the smaller light, only where it’s really needed, and then include copper in the larger SS X6.
They’d both then be SS and Cu, matching “His and Hers” lights if you will! Sitting in the case as a gift, they’d be a jaw dropping pair of lights to be sure!
Edit: Optionally, the SS could be dropped and Aluminum used with the copper pill, polishing the alum and using a clear or non dyed Ano. Cheaper body materials, lighter weight, Cu only where it’s needed and still a shiny bling bling look.
one Aluminum (Al) set.
NW , XP-L HI.
Some interesting suggestions on improving this setup! We will discuss them all and see what we can do.
Keep in mind that these lights will be Serial Numbered…so… the sooner you get you name on the list, the lower the S/N you will receive!

Putting my name on the list, is that a commitment to buy??
With this group buy I’m not very sure of which set yet.
13 is an unlucky number for some people. If mizjif and djozz would prefer my number, I'd be happy to swap places and take the unlucky 13... 
In my background culture 13 has a rabbinical significance...
Would you be willing to do that for us guys?
Nice my serial number coincides with my age 
Is an X6R out of the question instead of the X6?This would be the excuse to get one.
I’m in for one Al NW set
Can I get it matched to the serial number of my aluminum set?
I am in for 1 SS/Cu NW. If possible, would like to be #33. Thanks.
Man I’m drooling over this, especially if they can be mixed SS/Cu as per Dale’s post.
Anybody offer to buy one at full price then sell it to me for $40?
…
…
Jk!

…
(only a little kidding)
I'm in for another premium pair please.
But only if this makes me number 31 in the list! 
With the additional two (mattlward & abang.tegak) before me it should be...
Hirsh
Please one set SS/Cu NW. Thanks
Ciao
SS/Cu NW one set. Thanks
13 is an unlucky number for some people, so I guess 31 should be the opposite?
Nice….
Please add me to the list.
1)SS/Cu NW
1)Al CW
Thanks
Slow
I’m in for one AL set in NW (hopefully in an A or D tint…I HATE Green!)
Way Too Much Heat for SS - On the other hand I would like to add my voice to Dale’s here about the possible CU/SS or CU/Al hybrids.
Have to wait and see if this will be done though, so just the AL set for me now.
XP-L “Hi”?… Only if there’s no Green…. Really, really Hate that DD Green:-(
Hey - Thanks Kronos!!!
-Chuck
OH - and Please keep the head of the K6 in the same “proportion” as the X6 - IE… NO Full size X6 head on the smaller body! - Thanks!
