Thrust.

at 120, before the job advance, you should have enough SP to max every skill, and have 21 points for either thrust or inferno. This includes maxing MB, Hawk, Strafe, Rain, and Puppet. With a higher lvl bow/xbow, you should get at least 10 speed, and possibly 2~5 speed from equips other than bow/xbow. With 10 thrust, you get an extra 20 speed. That gives you a total of 132~135 speed, just 5 from having haste speed. Beyond lvl 10, you only get 1 speed per point into thrust. But 10 is really the recomended amount to put in if you are going to. For me, I plan to stick the extra 10 points ill have into either inferno, or to max focus, or possibly PKB and some into focus.
