With the exception of the extreme taildragger operations seen on the Valdez Alaska STOL competitions, I have never heard of a prop touching the ground during an otherwise normal wheel landing. I wheel land every taildrgger I fly, I simply find it easier to control the aircraft, easier to see where I'm going, and it saves needless wear and tear on the tailwheel.By the way, that particular flight school would not teach wheel landings because (they said) too many students were putting the prop tips into the asphalt.
There are those who will tell you that you have better steering control with the tailwheel on. At speeds slower than 15 MPH, I would agree. At speeds faster than 15 MPH, it's the rudder doing the steering, not the tailwheel anyway. I have proven this to myself with glare ice lake crosswind landings, where I was entirely able to maintain my heading with zero tailwheel friction, until slower than 15 MPH (when I could not hold the tail off anyway).
If a flying school cannot or will not train both types of landings, that is important information for the student in choosing to learn to fly taildragger there.
