All getting a bit esoteric for my little peabrain. My ASI reads IAS and I tend not to fluff about with whizzwheels and what have you when trying to plant the wheels as close to the downwind end of the runway as possible. A reasonable margin above the number where she normally adopts a more downward trajectory generally suffices. As for the old chestnut about attitude for speed etc, I tend to come down on the side of the little Mexican lass; "why not both?" Most of us have mastered (I hope) secondary effects of controls and tend to apply that combination of inputs required to achieve the desired result. Teaching attitude for speed is all very well as a teaching device, but imo is not to be slavishly adhered to once one has a degree of familiarity with placing said aerial device back on terra firma.
