.80 or .70 gated housing

Starting to rework the compounds on my truck. The primary charger is a S475 with the 1.32 ar housing I recently bought a 62/68 fmw charger and want to put a gated housing on it. Would I be better off running a non gated housing and running and external wastegate of could someone point me in the direction of a wastegated housing. I'm also wanting to hear anyone's experience with the .70 ar housing or the .80 I'm debating between the 2 if I can find them in a waste gated setup.

Personally with a smaller secondary like that I would run the .70 gated housing.

What does it have now? If its a .91 or 1.0 I'd consider running it as is with no gate depending on your power goals.
