Light skin is what I used. Holding up pretty well.  I've been running 6.5 front and 8 back on dirt.  Maybe a pound higher if it's real rocky. 

Sorry about the photos.  Here you go.

Quick update:

Bike weighed in at 23.2 final weight.
Raced it this past weekend and am very impressed with the whole bike. 

[Edit: photos are in post 11 and 12]

Here is my build thread.  Goal was a relatively light weight fat bike I could ride anytime of the year here in New England, so here goes:

After some research I settled on the Carbonspeed 197.  I had emailed with Peter about frames and wheelsets and found him to be quite responsive.  So I ordered the frame, 029 fork, axles, headset and a 68mm carbon wheelset.  Everything arrived about 10 days after ordering.  I have to say I was very impressed with how well everything was packed.  Wheels came in their own box.  It took me a good 15 minutes just to removed the bubble wrap from the frame.  Everything looked great.  No blemishes.  Everything looks finished to a high degree.

My parts list:

Jumbo Jim 4.0 tires tubeless
RaceFace Next SL crank/BB with a 28T
RF Next bars
FSA SL-K stem
FSA SL-K post
XTR brakes/Ice tech rotors
SRAM XX1 shifter/cassette/chain/derailleur
Selle Italia SLR saddle
Time Atac xc-4 pedals

Routing the shifter housing was a slight pain.  Definitely easiest back to front.  Those chainstays are narrow!  Brake line much easier.  Awaiting a stem before cutting the steerer tube.  Wt. 23.4lbs.

Few pics.

Tybiker, I'm looking for info on running the rear derailleur and rear brake lines.  Are there sleeves?  Any difficulties?  Do they rattle?

Sleeves? Do you mean internal guide sleeves? There aren't any of those, but there are plastic removable caps where the routing goes, which makes it easier to find the loose end when pushing through the frame. Mine have never rattled.

Yes, guide sleeves. 
My 197 is in transit.

How did you get the brake and cable lines through the holes in the frame?
Is there access on the underside of the BB?

There isn't access, but there is a lot of room on the inside of the frame near the bottom bracket. I just used a small metal hook and helped it through with the bottom bracket uninstalled. Takes a minute, but it's really not that bad. I started from the bottom of the chainstay and worked up towards the head tube.

Cool. 
How long did shipping take once it got to the shipper?

I'll be using a 32/20, which is good for our New England terrain.
