I have an Otto Link Super Tone Master for my alto, but I don't use it very often. On my tenor, the Super Tone Master sounds great, but on my alto, it's a little too bright and shrill at times. Otto Link makes a hard rubber piece that I like much better for alto, and www.wwbw.com sells them for around $65. The Rico Royal Graftonite mouthpieces sound great also and they are under $20.
