Which POF 308 should i get 14.5, 16.5", NP3,Black?

[alpha6164]

I am looking to get another semi 308 and have been looking at the POF variety. I have an FNAR 20" which is a solid 1/2MOA rifle so i wanted something a little shorter. I am trying to decide if i should go with the 14.5" or the 16.5" version? Also whether to go with the NP3 or black anodized finish? I like the idea of the NP3 cause i think it will be more durable. All inputs appreciated.
