If you are in the habit of starting flare at 30 ft and floating several hundred feet down the runway you may think that a full flap flare with engine idle is impossible without excess airspeed.
If you are used to making minimum energy landings I would not expect you to have any problem making a flare with full flap and engine idle. If you do, check the CG position and adjust it further aft as required to increase elevator authority. A case of drinking water at the aft end of the baggage compartment does wonders for the flare characteristics of some types. A jump master moving to the back wall of a C-182 jump plane is just as beneficial.
My current ride has 46 degree max flaps and they are very effective. I don't have a problem with idle power flare to 3 point landing but the flare starts quite close to the ground and the approach is a lot steeper than 3 degrees.
Know your aircraft and, if you don't know it well enough yet, move incrementally closer to the corners. You may be surprised what it can do.
