Tow Plane Upsets......

Sounds great to me! In the US, high tow is predominate although low tow is taught.
Our club is one of 2(?) in the US that predominantly use low tow although we also teach high tow.
We have tested "going too low" and the towplane still has elevator available whereas going to high runs the towplane out of elevator.
If the glider pilot gets way out of position, the time difference is not much between the 2 tow types in my opinion.

Not trying to start a "conversation regarding which to use", just noting what we do. This can turn ugly fast, even worse than US contest rules discussions.......

PS, lost a friend during tow a couple decades ago while he was towing with a "known squirrel" on the glider end. The towplane was a L19 and went in from about 300' when the glider went too high in front of a couple dozen onlookers.
Not sure low tow would have helped.
