haste gearFollow

i was looking at the BS 1H maces and saw dragonspine trophy mentioned somewhere. so, now i'm wondering, what's the most haste a warrior can get for himself, and which items/abilities should he look for?

1) flurry
2) mace proc
3) abacus trink (2 min cd on use)

are all i've got for haste atm. i would try to do some math but i'm at work. other than the dragonspine trophy, are there other items with a haste proc?
