Marty, I used to always keep a little power on in the flare, but with more practice (mainly, I think, in respect of judging flare height) I now typically have the power right back on landing. As others have said, you can pull the power right back on downwind, but not if flying a typical pattern at a busy airport.
I’ve landed at quite a few short grass strips, often with trees or powerlines on the approach, and the steep approach you can achieve with power right back, full flaps and full sideslip makes this very easy and comfortable (for the pilot, anyway!)
The keys to landing the SR2x really are, as most agree, getting the speed right and judging the flare height right. Until you learn to judge the height, keeping a trickle of power on (as in just a couple of mm movement of the throttle) in the flare will allow you to “feel” for the runway while maintaining the correct landing attitude and a controlled sink rate.
I reckon my “greaser rate” is about 98% - way better than I (and maybe anyone) could do in a 172!
