Try that coming over our tall western trees with most standard

landing.
Flaps are good for short landings but it's also possible to get
high drag steep approaches with a Standard class glider. My
ASW28, and the ASW19B I used to fly, have a very high sink rate
in a full rudder slip and the speed is easily controlled if the
pilot maintains proficiency. The hard part in practicing the
full rudder slip is getting high enough on final to be able to
maintain a stable slip without undershooting.
Been there, done that, in both standard class ships and Duos. It's
a whole lot easier to come down steep with decent flaps. Just
shove the stick forward, pull on full flaps, and point the nose at
where you want to touch down...

You make it sound easy Marc, but try that in a cross wind (slipping
to maintain correct heading) and you will find an undershoot
situation rushes up really quickly! I have over 1400 hrs up in PIK
20Bs and am still learning the fine balance between flap settings and
slipping on finals. Remember, it's generally better to land long than
short.

What makes it easy in the ASW 20 is you also have spoilers, which allow
you to easily adjust the glideslope without changing the flaps.
