After much searching, I have finally found the ideal crack pipes sold online ... in, of all places, the Amazon Home & Kitchen section, listed as "Clear Glass Pyrex Drinking Straws".
It wouldn't sit right with me to teach newbies the finer art of smoking base, but if you are already of that mind you can't go wrong with these stems. The aperture is perfect, the length is luxuriously long, you can get monster plumes of smoke while not wasting the precious product.
Whether you prefer the straight-shooter or the bent ones is a matter of opinion; they both are superb. Bell-ringers every time.
Cheers!
If you want the real authentic crack pipe hitting experience wait till your jaw is grinding so hard your chipping teeth and sketch down at dawn to break your neighbors antenna off his car before he comes out to go to work.
