Ideally you want the lowest idle you can get, that's not going to stall the engine on final. It's worth a bit of effort to try and tune for a lower idle, but this is the idle with the engine being driven by the prop, which is a different area on the tuning chart to the idle when stationary. You can only tune this area while airborne. I found this out when I first throttled back all the way on a high base, and the engine stumbled. I needed new underwear that day. So - lesson learned - test the throttle all the way back at altitude over the field before doing it on short final.
