Hi FletchPic:
Honestly some times I feel a little less ramped up and have a peaceful mellow feel or want to maybe get a little bluesy, that is where my Taylor 320 comes into play. When I am playing Bluegrass , Country and some rock is where the Taylor 310 really does the justice to those types of genre I love. If I had to give one up which I do not I would let go the 320. The 310 is the best all around out of the two.
Now let's throw a cat of a different color into the mix. I recently bought a Taylor 416 with a spruce top and Ovangkol back and sides. This guitar believe it or not has become my go to guitar and handles Bluegrass nicely and can be heard in the jam and holds it's own against any other guitar in the mix that I play with. I know it will be great when I get a chance to play it on stage in a little while. I am a Mahogany lover and always will be, but there is something magical about Ovangkol.
