NP man, like I said, won't really affect performance from what I've seen, it'll just be quirk that annoys you more than anything.
It's hard to think about the ptfe side not being the weakest link when comparing the wpb cuben varieties to the standard ptfe faced with woven fabrics which are inevitably the "right side".
The spectra on the NF is really just laminated directly to the ptfe layer. However, in this case, for being the equivalent of a "two layer WPB fabric", comparing say to 2-layer eVent, this stuff really excels, since it's much lighter, yet doesn't really suffer any new draw-backs in the appropriate applications.
BTW, forgot to mention it, but the jacket looks great. ;)
