Getting all the 3/4"x1" pine to lie flat,stay together, and not warp when it gets wet (and it will get wet, regardless of any varnish, paint, or fiberglass) will make you much happier with the aluminum. The time saved will more than make up for any cost difference for the materials. The rudders on Lightnings are essentially sheets of mahogany plywood, radiused at the leading edge and tapered on the trailing edge. If that was good enough for Olin Stephens, it should work for you in aluminum too.
