I always preferred brass screens. I tried stainless steel and they do last longer but they would clog up fast. With brass I'd have to burn the screen like every 3 or 4 bowls but the stainless steel needed to be torched after every bowl.
The most annoying pipe I ever owned was the protopipe
http://www.xtremecollection.net/xc-mppp.htmlIt was a good pipe when its new but once it got dirty it was a major pain in the ass. I preferred the cheap anodized aluminum pipes. Standard sized, easy parts to replace and cheap enough that after a few months just toss it and get a new one.
I like brass too. The SO keeps trying to get me to accept the glass ones. Stupid, overpriced getting lost in the carpet things.
If you think you hate protopipes, you'll really hate the Chinese version. I bought a dozen a couple of years ago to put a skin of polymer clay on. The looked pretty cool, but were just terrible quality. About half the price of the regular ones, but talk about your pieces of shit. The pokers just would not stay in their little holster.
I like the aluminum pipes too. I sell a ton of ones with a camo pattern on them every hunting season. Cheap parts, little labor, nice profit margin. Ah, I'm doing the Lord's Work.
