welcome to the forum. I have two that I got on the special they ran for forum members a while back, their not part of my regular rotation but sometimes when I have one of those tobaccos that a family member thoughtfully gifts me because it sounds tasty(read sickenenly sweet aros) the magic inch pipes are the perfect thing. They cut down on the over sweetness of some casings and make the choco/nilla/berry/honey flavors come through a little more. You do have to pack them significantly looser than other pipes. Also the air flow does serve to slow your smoke down a little. All in all their not bad for tobaccos I really don't want ghosting my other pipes. But, if it weren't for syrupy aros biting without some sort of system like this, I'd say the same thing for cobs.
