Doc, I'm actually considering the same thing, as my 13 gets held up going into a headwind. It's great in a tailwind, but hurts going in. I'd have to give up my 19° hybrid (leaving my longest option off the deck into greens a 22°), but would be good for other courses I play.

Of course, I may just switch to an 10.5 or 11 and keep the 19.
