Glad you like how it sounds!
One of the things that helps make it great, both for tone and ease of maintenance, is that it has carbon fiber truss rods instead of an adjustable metal truss rod. I don't know if that's still an option, but it's great.
First, the guitar's neck has remained perfectly straight for almost ten years, no issues, no maintenance at all.
Second, the resonance of metal is different than that of carbon fiber. The carbon fiber seems to not ring in the audible frequency range, or ring less, and I find the guitars with the carbon rods sound 'woodier', more even up and down the neck, and more natural (this is my second PRS acoustic with carbon fiber, and I've had guitars with maple bodies and a similar size with metal rods that emphasized certain notes).
So I'd recommend the carbon fiber rods highly. The choice just works better (for me - your mileage may vary, price does not include tax or transportation fees, do not taunt Happy Fun Ball).
