I have no idea. But I do know back in the early 90's we use to call isobaric "TWF", back when it was first gaining popularity. Wondering if that's where you got your name.
Anyone care to guess what it stood for? //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
