Getting ready to purchase a couple of rotary saws. We've used 12 inch for as long as I can remember. Is there any real advantage (or disadvantage) to going with 14 inch saws?

We plan on setting one up with a composite, metal-cutting blade, and the other with a Warthog. I have heard that the Warthog performs better on a 14, because there is more room for the chips to clear, and the guard doesn't clog as fast. Has anyone found this to be true?

Anyway - let me know what you think, and what your experiences have been. Thanks
