Mark,
1&3/4" is the largest nut width you will get on any Guild and it is currently only on the F30STD. I have played both the TRAD and STD lines and there are differences in the neck. The STD is a low profile neck very similar to a taylor neck, but a little thicker than the GADs. The TRAD has a thick beefy neck to accompany the 1&11/16" nut. Both, in my opinion, are easy to play fingerstyle. Currently, if I had my choice, I would prefer the thick neck with 1&3/4" nut width just like the Martin modified V. The only problem is I would have to buy a Martin. :wink:
To add to the Guild fingerstyle craze, lets not forget John Hurt who was able to play some pretty complex stuff on an old F30 which probably had a 1&11/16" nut.
