If you ask me, I'd mix between Erebor Huntsman, Hybold Bowmaster and Hytbold Huntsman.
So 4 Erebor, 2 Hytbold Huntsman (5B2R with Fast Draw traited, 0.9s induction for Swift Bow in Imp. Fleetness lawl) or 2 Hytbold Bowmaster.
Alternately you can go 2-2-2 like CAL88 said, though personally I like -mitigation% over critical multiplier. Or the 2-set bonus from Precision set from Ettenmoors. Would be interesting to eat through all the mitigations...
