A-26c Jersey Bounce question. Please advise

I've been working on Monograms 1/48 a-26c for some time now and need some advice on decals. About half of the sources I've seen (mainly decal sets) have the nacelles black with the underside wings black as well. The other half have only the nacelles black with the under wings nmf. I've elected to go with the black nacelles and underside of the wings black (see photo).

Going with this option means the black USAF and dark blue national insignia won't show up. That being so should I go with red USAF letters and national insignia left over from the original kit decals or should I paint the underside of the wings nmf and use the black lettering and traditional national insignia? Can anyone advise? @tcinla @fiveten @blackmopane @johnb and any others!?!
