My favorite has long been Ligna mane...aka Morning wood. It's getting more and more rare, but I found some last week.
I'm guessing that Ligna Mane has less movement than most other woods and thus an easier build, Rick?
I once asked a luthier for a ukulele made from Ligna Noche, or Nightwood, but when I showed him my curly wood set, he said it would be too floppy for a solid build. He said he would have to add extra bracing and animal glue it directly to my topwood; I informed him that I was raised in a God-loving home and the mere mention of his unorthodox bracing made me sick, thank you. He went on to say that, since I stored my wood in a very humid environment, it would likely shrink once built. He taught me that shrinkage might adversely affect playability, and we certainly want to avoid that. He said my set seemed small to him, perhaps he could manage a sopranino from it; I told him that I always thought of it as a tenor set, if not a small baritone. He laughed. In any event, he recommended that I air it out for a while, let it breathe, which I did since he's the expert. If that'll stiffen it up and avoid bellying, I'm all for it.
In the meantime, I begged him for anything that might work right away with my low G string. I was desperate for something with a tight waist and perhaps a side sound hole. I hate conflict, so I asked for a zero-fret model and to avoid friction pegs.
He told me he could do all that, but that I should go with Bubinga. I asked him why, and he said that it's because he likes to say Bubinga. Boob-ing-a. He gave me a little pronounciation lesson and insisted that I hold my mouth a certain way when I said it. He assured me that it would have a sweet voice, a thin neck, would play fast and loose, and that I'd want to strum it all day and night. The luthier said that he does a light application of Tru-oil on the body, but his signature piece-de-resistance is a French polish for the headstock. That sounded irresistible! He said I'd fall in love with it once it opened up and I put a strap on it.
He cautioned that it would cost a lot of dough, so I asked that he include a genuine fur-lined case. He declined, saying that foam-lined is nearly as real, plenty adequate, and gives almost the same feel.
Almost the same feel! I said to him: "What are you? Some kind of pervert?"
