Crosswind technique.
I’ve personally never used the wing down method on finals. The benefit of crabbing a taildragger, particularly a long nosed one like a Tiger or Pitts, all the way to the flare is that I can see ahead. Straightening the nose and dropping a wing the appropriate amount is easy enough in the flare.
That said, my preferred approach method was a constant turn, but traffic doesn’t always allow for that.
