Hi,I'm a Generation girl myself. Don't like Clarkes... sounds too breathy. Susatos (plastic) have a beautiful sound (can sound like a recorder) but I don't like the mouthpiece... it's too short and I tend to play out of the side of my mouth, a combination which just doesn't work with a short mouthpiece. I just don't trust it to give me an accurate top octave.
I love the sound of low whistles (you know piece of drainpipe with a mouthpiece on the end), unfortunately they are just physically too big for me to stretch.
