Having trained power in J3C for PPL after gliding, I concur with the necessity to know wheeler.
When the wheeler becomes one wheeler before slowing down, I'm still not that great, but that's for other reasons. In those circumstances, if having to land (ie wind picked up after take off and not expected), I'd not hazard full stall with one mail wheel up.
I also find it harder to do three pointer in tarmac/concrete compared to grass.
In light tailhweel like old Cubs, it's not as easy to do full stall 3 point landing, compared to wheeler, too. I need to get some tailwheel currency. Super Cub and Citabria should do this summer.
