I had lot of cable breaks this year and no problems with the speed. You've
only to react fast enough. And the 21 is a very friendly flying plane (with
our other planes, especially the ASW19 I prefer higher speeds on winch
launch) and you normaly are not pulling the stick full back before you reach
the safety high.

What do your instructors say about using back-stick in the K21?

I just did my annual winch-launch checks and mine wouldn't let me use
any back-stick at all. A K21 will still launch perfectly well like
that but I *know* that I'm not getting the best out the launch like
that. On the other hand my instructor did play a neat trick on me - he
distracted me by suddening say "look at that plane!" and pulling the
release at the same time. I *did* hesitate in getting the nose down
and even though it was only a small delay by the time I'd finished the
push-over to the recovery attitude there was only 40 knots on the
clock. Took a fair few seconds to get the speed back up before braking
down to a straight-ahead landing.

That was a bit of an eye-opener, to be honest.

Well, if you have the stick fully back (which I often have, and don't object
to with my students), you
1) are above safety altitude
2) pay attention.

- already have a significant nose-down force by cable tension because
of your height

The same as in any other glider: Use as needed to keep your target speed.

That's what I think but I put this specifically to the full cat* I was
flying with and he disagreed, saying "you'll risk spinning on the
wire" if you use "any" back stick in the K21, and that you should ride
the speed with the elevator neutral throughout the launch until you
need to wave-off (signal the winch driver to slow down by waggling the
tail).

*in the UK there are three categories of instructor: "full" is the
highest, the others being "basic" and "half"
