You can dry as many flakes as you like. I normally take 2-3 SG flakes which are pretty long, probably about 6" or so for the bulk flakes. I rub them out into a nice shag, dry and fill up a couple pipes at once. For the Mac Baren, usually two flakes will fill a group 5 or so pipe if rubbed into a shag. Have not tried the cube cut method yet.
