Chuck and I have previously discussed wheel landings vs. 3-pointers. While I personally favour the latter for most conditions, I agree with all of his comments posted above.
I doubt if a school here in the UK would require the demonstration of wheel landings for the purposes of "checking someone out" to get a tailwheel endorsement...
I don't want to 'shoot the messenger', but this makes absolutely no sense to me; what kind of check-out is that? It would be like omitting sideslips.
