Vince, that correlates pretty well with my experience. I never noticed any control issues because I almost always had to screw the power back on to make the field. The few times that I did make it was because I turned base immediately after I reduced power to idle. As for the assertion that the clutch is no worse than an engine out with prop stopped, once again, that's not my experience. The clutch is great for seaplane and towing where the landing field is alway below (watching a Moyes Dragonfly do a reasonable imitation of a Ju-87 Stuka after releasing me from tow was a sight to behold) but beyond that it's not for me.
Should anyone out there in the ether be considering the Rice King, do yourself a favor and put a couple of of tapped holes in the back plate (3/8-16 UNC or 10mm X 1.5 seem like a good compromise between size and strength) so you can remove it should the need arise. It was a major PITA to get off, but now I own a customized puller should I ever have to do it again. :-}

My experience of declutched freewheeling propellers is that in event
of engine off, glide distance is significantly reduced, perhaps worse
than half.
This in turn cuts reachable landing spots to a quarter as well as
reducing time available. Yes you can use it intentionally like a
spoiler or flap, but you cant "reduce flap" to penetrate ahead.
Also the disturbed airflow over the tail can give you a nasty surprise
whe you try to do an accurate landing flare
