Wyand, I would sim not just patchwork but light movement and helter skelter modes. I'm going to guess that KTT will come out ahead since getting that CB off at 10 stacks is big but missing it really sucks. I might favor KTT for progression/consistency and BB for trying to rank the same way KJC vs AD is a tradeoff. If you are running gosac w' destro KTT scales well. Look at your version of simC's APL for any code relating to use of CB and trinket procs....been awhile since I looked (and several versions) but IIRC it does use CB's during trinket procs by default. Both work, both are probably pretty close, its just easier to get hosed by RNG with BB. However for aff/demo BB > KTT so if you want a single gearset consider that as well.
