I've been smoking this Radice Rind hawkbill for a couple of years. It has been just "ok" -- it found a spot in my rotation easily enough, but had never produced a really inspiring smoke. My main criticism was that while it passed a standard pipe cleaner smoothly, it wouldn't pass a thick-bristled pipe cleaner because of the diameter of the draw. So yesterday I worked up the nerve to straighten the stem with heat, ream it out with a #32 drill (~ 3mm), and restore its original curve. Now it's smoking like a champ! It is absolutely amazing how opening the diameter of the stem improved the pipe!
