Ground effect exercises helped me no end with my finesse. Especially x wind.
Fly the machine down the centreline as best as possible with a bit of power, and try and stay in ground effect. Look at the end, not out the side.
You get used to the slushy controls, the closeness of the ground, and if there is a really longish runway, you can kiss the wheels a few times.
Made a lot of difference for me, as my flare was too high, and I was trying too much.
Gliding, now that looks like great fun. Must get to that one day.
