As I understand it, during prohibition if you ordered tea you got gin, order coffee and you got whiskey - both served in cup and saucer. Nowadays you can only get coffee and pay as much as you would for a double whisky!
On the original subject, I like the velcro straps as they don't loosen in play, whereas the rotella type can. Either type of air button can be operated with subtlety once you get used to them. Worth noting that Hohner Clubs have the "Italian" type before they cut every possible cost and produced the Pokerwork. Some of the bigger Clubs have two pallets linked to the air button. They also had much better reeds with an impressive dynamic range whereas the Pokerwork tends to on/off unless carefully set by an experienced fettler.
