Forward slip in glass gliders won't get you much descent;

The ASW-19 and ASW-28 have a huge increase in sink rate in a full
rudder slip compared with airbrakes alone. What glass gliders are
you flying that do not slip well? Can you maintain a full rudder
slip, and I mean rudder on the stop and never comes off it until you
choose to exit the slip?
