McDougall,
Didn't you buy a myrtle MM? How is it? Do you like the sound and play-ability?
I am curious why you are only looking for MM.
And one word of advice, if you believe in a "Holy Grail" uke/or a uke to "end your UAS" then you will be looking all your life.
(And this from a guy who two years ago swore that a Pono MGT would keep him happy and didn't need any other ukes.
I have since owned a KoAloha Pineapple Soprano, a Pono MTD and a Breedlove prototype tenor. And I am now going to have a custom cedar/walnut tenor made by Ono ukes.)
My 2 cents.
