The high AoA/High Power approach in Cherokee-type Pipers is a rather poor description of the typical POH-recommended Soft Field Approach. This mechanism helps to control the rate of descent on touchdown, and avoids premature digging in of the nose gear. It almost certainly doesn't apply to short field approach.
Although I have no Cherokee 6 book nearby, I would expect you to find that the approach should be flown in the normal approach configuration (full flaps), but at around 5 knots slower than the conventional approach.
On touchdown, which should be accurate and on the numbers, the flaps should be retracted in one smooth movement, and the brakes applied with the control column held fully back.
I would be surprised to find any significant variation of that technique in any checklist for the type. As others have written though, you should trust only the approved POH in matters like this.
