CT,
It has been a few years since I have flown the PA18, but I seem to recall that it is like the PA17, where you just bring the stick back for a three pointer, but G-DRAG is definitely good for good habits in that you have to positively set the landing attitude visually, it is easy land tailwheel first.
I haven't done a wheeler in G-DRAG, they weren't recommended by DS for one.
Perhaps it is the photo angle, but Chuck's piccie seems to show different legs?
