I'm no expert- but looks like a totally different thing than DCF.
One reason I'm not an expert- what is the point?
Cuben Fiber (now DCF) is a wonderlite fabric. You pay the big bucks for the low weight.
Once you start crossing the 1.0 line there are lots of options.

In the PU coated version (if waterproof is a reason for DCF) you're at 3.2 ounces per yard (vs 2.92) for a pretty bomber pack fabric for $8.50 per yard.
If you have to do much extra reinforcing, taping, or laminating on the pack... the DCF ends up about the same weight.
There are plenty of other things to list... and plenty of gearmakers like Gossamer Gear I could point to who use much lighter fabrics than DCF successfully.
There is the whole xpac discussion you could have as well.
I've built plenty of stuff with various sil-nylons. The Hybrid 1.7 is pretty bomber fabic, easily backed up by a trash compactor liner.
Sorry for the slight rant... but if you like DCF use it.
If you want to save weight and/or money there are lots of options.
DCF is an amazing tarp/shelter fabric in weights 1.0 and lower. It puzzles me though why folks stick with it in packs or heavy use when there are often better options.
