CRUISE altitude and throttle oscillations

My T-2 Cruza VTOL seems to fly well in FBWA and ACRO after autotune, however I am getting a fair amount of altitude and throttle oscillations in CRUISE.

Looking through the TECS tuning guide it seems like increasing TECS_TIME_CONST may be the next step, though I also see TECS_THR_DAMP.

Is there one or the other of these that is better practice? Any other things I should be looking at?
