By the way, did you see my whistle review? I wondered if my experiences with the Susato mirrored yours. I can't remember!
Yes! I saw the review! Your assessment of the Susato is just like mine. I love it but nearly pass out playing it. It's why I like my Mack Hoover. It's as loud, but takes half the breath.
I almost bought a Sweettone yesterday, but I don't care for the conical whistles...I like my cylindrical type! I seriously believe it's just because that's what I started with.
Did you see these? Lord help me, I love them, especially the Summer's Evening with Stars (which reminds me of Eowyn's mantle). Of course they are hugely expensive.
