With my limited tailwheel experience, I can't say yet which is better for me, but I know more than one experienced hand- including the guy who checked me out for my tailwheel add-on, who'd been giving lessons in that very plane for
over 40 years- who say "I don't care how hard it's blowing, or from what quarter, I'll always do a three-pointer." I'm sure there are equally savvy old birds who'd disagree, but I haven't heard from them yet.
As stated earlier, a 3-pointer is not necessarily a full-stall landing. You can put most light taildraggers down on all 3 wheels at a fairly wide range of speeds.
I'm inclined, so far, to lean towards the 3-pointer camp, and here's my logic:
OK, so maybe keeping the rudder high longer will give you more yaw control longer, before you've committed the tailwheel to the surface. But there will still come that moment when the tail must come down, and you will find yourself, at that moment, in precisely the same situation as the guy trying a 3-pointer. So why put it off? The tail wheel, if steerable, will give you much better directional control than the rudder, in most cases, so it seems logical to bring it into play while you still have most of your runway remaining.
Personally- and again I will state I am a pretty green taildragger pilot- I have found that the more important thing in x-wind landings, in a Champ anyway, is to get that upwind wing down and keep it there. People have ground-looped or veered off the downwind side of the runway out of wheel landings because they failed to do this, believe me. And again, no matter which landing you do, you still have to roll out, and that's where the footwork really matters.
And you can always go around, unless you were very negligent setting up your approach. My tailwheel instructor told me he was most impressed with my willingness to go around if it didn't look like it was going well...especially if I bounced. Even a little. That is when a 3-pointer in a xwind can get really ugly; better to open the throttle and go around than to try to save such a landing.
