From what I've seen most people attempt to use flaps when they really want spoilers. Flaps are used to allow a steeper glide angle without an increase in speed. What most people want is to fly with a constant "flare" or nose-high attitude. This is permitted by spoilers, not flaps. Flaps cause you to fly with a nose-down attitude up until the point of flare immediately before landing. I think the tip-stalling comes in with flaps when people attempt to flare too soon.
