Put simply, kiting accidents just don’t happen on low tow. The only time I’ve ever seen a tug upset was a glider that had to use high tow
fortunately, the glider released immediately and landed ahead. Again, to be simple, the tug is at all times visible to the glider pilot, it cannot disappear
under the nose, a feature unique to low tow. As for the small height gain, I have the opposite view, being lower gives a better chance of straight ahead landings.
I can’t recall a single accident caused by an upset in low tow. I stay as low as possible after lift off, and wait for the tug to climb above me and stay there.
As my glider has winch hook only, I would not risk the tug pilots life by doing high tows. All I’m seeing is spurious arguments in favour of high tow, that put the risk on the tow pilot not the glider pilot.
I’d rather crash myself than kill an thuggish, but that’s just me.
