Me either, until a couple of years ago as I watched my supply getting low and the need to replace it approaching, and decided I'd better start researching what to replace it with. Decisions are easy, it's getting the information to make good ones that's hard. > So here's my question.

A film of the stuff, meeting standard (?) testing parameters of water concentration and thickness, has a specifically shaped probe pushed through it. The pressure it takes to do this determines the gram weight grade of the glue. The easy way is to buy a pound of 251g from Pianotek and compare it's working properties to what you already have. If you don't like the 251g, buy 192g elsewhere - like Milligan&Higgins. I suspect you probably have been using the 192g. > Thanks for sharing your knowledge about the subject.
