How do you do a coordinated turn without rudder input?
The flight manual we used was wolfgang langewiesche's "stick and rudder", he spent quite a bit of time warning about the skidding turn (i.e. excessive rudder), especially on turn to final. The slip, of course is something quite different and as you and Densell pointed out is very effective in losing altitude quickly without gaining speed. I have done it many times, not dangerous at all if done correctly and actually a lot of fun.
You have a lot more flying experience than I do, so maybe I am just misunderstaning something.
