I have no idea what this talk of orbs is.
Chaos Orbs are used for crafted goods, not enchants.
I did a check today for what is selling; especially since
Maelstroms have dropped significantly, and
Heavenlies have risen quite substantially. It seems that right now, the most profitable enchant is
Bracer - Greater Critical Strike. It takes a fair investment, but the return is really good.
As for tried and true, I will echo the above sentiment:
Hurricane and
Superior Intellect are still good.
Gloves - Greater Mastery is also profitable right now. Just bear in mind that
Maelstroms will only drop in price all the more. Prices are not yet stable - but looking at TUJ you should find a lot of movement for most of the high-end enchants. No better time to start selling them than now, before 4.2 hits and while
Maelstroms are at an all-time low.
