Congrats on the purchase of your Cruisair! fun
As I recall, I used all the flap I could on short final, even thought of the possibility of adding more as a split flap inboard. (if one is a masochist, STC's could be fun) With a lot of flap, the ailerons are great right down to the stall. A baby doll to land. I always used full flap. A crazy crosswind might be an exception, but even then, the manual flaps can be dumped in half a second to get more weight on the tailwheel.
Approaches I did at about 80mph and a couple of notches of flap for traffic. Considerably slower is also OK if you are light. Probably lots of varieties of opinion on this subject.
