Hey Blue,
Those are 2 great guitars. Although we are not a Collings Dealer, they are certainly among the top of the heap in terms of quality/tone. We are very particular to Bourgeois as you might expect. I personally think nobody does Aged Tone like Dana. I've played them all and he has mastered the art of the "broken in" aged guitar. And they aren't too hard to look at either
Anyway, best of luck in your quest. If you decide on the Bourgeois let me know and we'll get you the AGF'er deal
Take care, Brendan
