I found the perfect setup for my Classic flash was 22 1/2 degrees of takeoff flap and 45 degrees of landing flap with 6-8 mm of crow mixed in. I found my best approach routine was to go straight to full flaps in the middle of my downwind leg and drop the throttle to about 3 clicks off of idle (with a 31 lb thrust Cheetah). This would give me a nose up attitude and predictable sink rate which was easy to judge when on base plus I still had some room to come off the throttle on final if needed. Then just chop the throttle and let it sink in on the mains. I actually found my Classic Flash more predictable to land than my Ultra.
