More Flow Or No?

[ReefMadness]

in my sps + zoa dominant 120 standard i've been running a gyre 150 for the past year. my impressions are the same as everyone else's i've been reading about, the gyre moves tons of water but is limited as far as creating chaotic flow with the single gyre and old controller.
to fix this i'm considering adding a xf250 gyre and the new controller but i'm not seeing it as a very common set up on people systems.
any reason i should hold off and do something else?
