I usually don't like to comment on things I have not personally used. However, I do use the Votaw Gorilla Expander on sax necks. It's the best expander I have used and I have tried all the others that are readily available. When I got it, I sold my Allied expander that week. I have to imagine that the Flute expander from Votaw is just as good. It's a lot more money though.
Votaw has a trial policy and Carl has always been easy for me to deal with.
