Adding to my concern is that the ubiquitous US Schweizer 2-33 does use full
up elevator on a winch launch due to the unfortunate position of the release
hook. A pilot transitioning to even a docile a trainer like a ASK-21 could
be in trouble if he misunderstands the difference.

True CG hooks were an option for 2-33s, and could probably still be
retrofitted if desired. A second Schweizer hook is mounted ahead of the
main wheel, to the left of the skid. From recent experience, the
handling during launch is similar to a K-13...
