I've enjoyed this thread. And yet no one has slammed the volcano: allow me. I dislike toothbender heavy pipes, swivel bit pocket pipes, pearly plastic or transparent bits (except amber), skaters, pickaxes, The Pipes, brylon (shiver), and yes, you'd think freehands wouldn't be so standardized. (Jazz can be that way, too.) Speaking of Oompauls- ever look at the backside of toilets? I'm just sayin'. Painted and shiny glossy pipes. Bamboo in anything but an aboriginal pipe. Meerschaum sculptures with a hole and a bit: bearded men are tedious, skulls are creepy. Tyrolean contraptions with chains, feathers, painted scenes, lanyards...
Pipes I should like but I don't: Porsche Design (full of itself), anything over $150 yet looks stodgy (Dunhill billiards). Fabulous briar that should have become carved art for art's sake instead of a pipe.
Pipes I should DISlike yet don't: affectation pipes like LOTR or MacArthur cobs or calabashes that look more like theater props (though I usually dislike their smokers). Grabows. Cigar pipes. Leather wrapped "piggy pipes". Glass pipes in head shops (I'm a chemist, remember). I have a few pipes that literally look like lumpy turds but I keep for amusement and humility. Aluminum Falcons (with cob bowls!!) are a hoot.
