Have you ever considered a steeply banked side slipping turn ?
You may have a high rate of descent, but the radius of turn is so
small that the duration is very short, making the height loss small,
and you do not need to increase airspeed to do it.


We know that angle of attack is the concern in stall avoidance....any
stall spin accident off of low rope break has to have had too much
angle of attack, one way or another....This means too much stick back
pressure....This is why I like to see an obvious stick forward and
nose pitch down reaction upon rope break.....also smooth control
inputs....

What is the benefit of slipping?



To keep the inside wing from stalling during the turn? I have read a few
articles which recommend "slightly" slipping in a turn to prevent a tip
stall. A few other articles which pointed out that for the yaw string to
be straight in a turn, too much rudder needed to be input (because addition
of thr the sink rate shows the yaw string offset to the outside)
