For once we're all agreeing !
Certainly when the grass trip here in Sussex England isn't tooooo soft (far too soft now; I walked it today) I do the same with the tail wheel Rans S6-116.
It always is a pleasant surprise how soon she lifts off from starting with 2 of 3 flap stages set and stick held back all the way.
Naturally once just aloft one levels off to gain a sensible speed before climbing away.
The technique is principally aimed at doing my best to avoid nose over tendencies if/when she hits a particularly soft patch.
So no finesse required.
Landings at full flap allow squirts of power to select almost exactly where she'll hit the runway, that is avoiding the known boggiest bits. Then she's beautifully responsive and slow enough to not worry if one lands long as the worst area cuts 200 yds off available length.
Funnily enough in Summer I revert to conventional flat roll to about 44 mph then lift off, though why I don't always use the Winter method - shurely shorter? - I don't know.
