Reefcrest and gyre mode with MP-40's for me...I have a cheapo Jaebo pump going across the back that's pulsing to produce a bit of a wave...it's on all the time, so on gyre mode things rip for 10 min then quiet to the soft standing wave, detritus doesn't have a chance. My rockscape is in the middle of the tank.
Jaebo was against my better judgement, but it moves more water than th MP-40, quieter too, we'll see about long term survival....you can but 5 of these for the price of a MP-40 though.
