What is the best tailoring recipe for producing enchanting mats in terms of efficiency?

Any good references looking at the economics here?

Thanks.

I've had success with disenchanting Netherweave Bracers. I'd say 80% of the time I get 2 Arcane Dust. If anyone knows a cheaper piece to D/E and get Arcane Dust I'd love to know.

Isn't 2 dust is the worst you can get for any outlands disenchant?

netherweave bracers = 18 cloth = 6g on auction
2 arcane dust = 4 g on auction -
Prices ma differ on your realm, of course, but more likely than not, the best way to convert cloth to enchanting materials is to auction the cloth and buy the mats.

I just shop for anything greater than 65 and 5-6g or less (depending on prices). Sometimes it ends up being something someone else crafted but usually not. I don't think there are really any patterns where you can buy the mats, create, and disenchant for a profit. There are, however, some that you will lose a lot less money on when trying to level up tailoring like arcanoweave boots instead of imbued netherweave once you get into the highest levels.

But with the dissenchantfest that ais our endgame the price of void crystals is dropping fast sadly, which makes this not all that great anymore.
