I got real comfortable with wheel landings on the L-5 when I started, but after vigorous recommendation from many people, I got back to three pointing it. When I haven't flown in a while, the tendency is to want to wheel land it- I guess all that time in the C-150 and C-172 hasn't worn off, and I get the sight picture better on a wheel landing. But when I remember that it is okay to turn your head in the cockpit while in the middle of landing, and use your sight picture from peripheral vision, the three points are easier to do.
I really believe that people don't like to three point because of the lack of sight picture. The guy who built my L-5 says that you are going to wind up with the tail on the ground anyway, so why not begin there in a landing flair? One other thing that I encountered one day. I overheard two people, one of whom was Art Nalls of Harrier fame, talking about flying the Yak-3. It seems that the discussion was about how much shorter five knots less airspeed allowed the landing roll out to be, but how scary not having sight over the cowling was. In the discussion, it seems that five knots less airspeed and a three pointer cut almost a third of the landing roll-out distance.
I agree that having the wheel landing in your tool box is a good thing, but I also believe that it has become more common practice in time due to the overabundance of tricycle gear time people are compelled to fly. Since it is so easy to abuse a nosewheel to make bad landings look good, that is what is happening, and it translates over to an over-abundance of wheel landings in tailwheel aircraft.
Ken, was that old Skyraider pilot Tony Markl? Great guy... He is a true master of the tail wheel, a complete gentleman who helped my family out when we had a small emergency, and I recommend that everybody who is inclined to fly tailwheel should spend some time with him. I also really like how he does fabric work.
