Question for SummNec Runner

Depends on what you're running. If you're doing act bosses mainly, then there's no need to add more MF, since act bosses are set up (on this server) to drop unique versions of the base items that they drop (so, if Nihlathak drops a sacred armor, it will be unique, since he is able to drop both TM versions - green and blue).
If you're clearing areas before getting to bosses, in my opinion you should stick to MF gain from Enigma, maybe add 50 from a Shako (if you have a gear combo that meets the BP's that you're aiming for). The reason is this: chances of regular / champion / unique mobs to drop a unique Weap87 or Armor87 item are so very-very tiny, that it makes no real matter whether you run with 95 MF or 350 MF, the difference won't be really noticeable.
To prove my point:
1. I've had such drops from map mobs with my 0 MF light sorc (most of them I posted in the Best find section); Griffon x 3, green TM x 1, Steelrends, Dancers x 2, DW and others, all with ilvl 85-88.
2. If you're curious about statistics, as I was), you can tweak you maphack to show base items and see how (in)frequently they drop.

TL;DR stick with MF from Enigma and go for kill speed, rather than MF %. If you want a specific item, the best way to get it is through trading, play the game with no expectations in terms of drops and be pleasantly surprised when they occur. But if you insist that a specific item drops, then patience is the key, as well as luck.
