I have built a few of Roger Mann's Ragwing designs from Fir. It is stronger and yet it is also heavier. If you are careful and take your time it is a great strong wood. I get mine from wood suppliers for cabinet makers. The source for my last shippment was http://www.edensaw.com/ and after grading it, I had alot of good wood. Of course the longest clearest pieces became spar caps.
