Standardization in Slack Rope Recovery?

After we've been flying on our own for a
while, slack rope situations become very
rare (except on Condor with which I am
getting through a problematic
introduction).

Instructors of course encounter slack rope
situations more frequently with
magnitudes where many of us would have
yanked long before. Flying a CG hook my
hand is always on the release during tow.

My bigger concern is instructors that want
to see a fully developed spin before
recovery. That builds a muscle memory
that will have you smacking the ground if
you get an incipient in the circuit.

I have a thankfully very short list of
instructors I will not fly with.

The latest addition said some years ago
there was some unidentifiable concern he
"could not put [his] finger on".
