Right now I'm running only 1 audacity piece (boots) & 5pcs faron. I've been spending my commendations on other chars (my hunter is actually r8, but this forum won't let me edit my sig without changing it to be about 1/3 of the length), but when I get a few more pieces of the hunter sets I'll macro the fleetness set it. 2/2/2 seems like the best setup to me, none of the set bonuses are particularly worth having.
If you don't want to use a macro I'd probably value the faron set over +5 audacity... It's that good.
If I'm in 5r/2b I'll either go 4 faron/2 pred for the extra PM or 4precision/2pred for the audacity bonus. If I'm running fleetness, I go 5 faron/1pred always for the penshot bonus. I find the extra pen shots more than compensate for the loss of audacity.
I go 2/2/2, using the max agil pieces. Shoulders/jacket of entrapment, gloves/helm of precision, legs/boots of predator. Not worth it to go down 4 pieces of one line imo, but I am working on full precision set now, just to try out that -25% CC duration lol
