I would be inclined to try a tuned pipe with that setup. I'm actually glad this thread gave me that idea; I've got a 46AX looking for a new home, and a pipe will surely open the door for more possibilities.

I've had a couple of Phoenix planes. Really great bang-for-the-buck. It is very common to get a Phoenix plane and be quite impressed with what you find in the box. They tend to run on the heavier side, but not too bad.
