I had a 96 JF30 12 (natural) a couple of years back. It has good sound and pretty maple blonde look.
Now I have a 88 JF65 12 (sunburst) and in comparison. I like the JF65 12, cause of the sound and sustain. I like the ebony fret board and bridge. It's got inlays on the fretboard and I think the neck is slightly skinnier than the JF30 12 (to me).
So my vote would be the JF65 12 or JF55 12.
