I picked a 16" for my first Grendel, But I also have an 18" AR10, the AR10 is a Tank and I wanted my Grendel to be handy, the 16" from AA is stupid light for it's profile because of the fluting. and generally I think it is safe to say 2 inches equal about 50 FPS one way or another, for what that is worth.
If (Read: When... lol) I build another Grendel, 20" Kreiger from Mark at PF, target crown. That would be the unicorn.
I think for the money the Criterion would be a superb choice as well.
