Hello,
Owned both, shot both, the Signature has a little bit better lens and the internal optics are larger, better light transmission in the Sig. Basically, the Fullfield is the Econoline, the Sig is the midline and the Black Diamond is the high line. If that 100 bucks is important to you get the Full. If you can afford it, step up to the Signautre. Either will work just fine.
