Gamelli

I am planning on buying a new guitar this summer and I'm trying to decide between the ES-347 and the B.B. King Lucille. The main consideration is the shape of the neck. I have heard that the ES-347 has a wonderful neck that is slim and tapered very nicely. I only play blues, how does the neck on the 347 work for blues? How does it compare to the Lucille with a fatter neck? Unfortunately I have not had a chance to play one to see for myself. Thanks in advance.
