high tow vs low tow

While I agree that "slow is slow", I think it's much better to be in
high tow position and be able to sink to low tow if the tug gets too
slow.Â* I've been dangling on the end of a slow rope with a full load and
had to start dumping while on tow.Â* It's not comfortable.

Of course that proper thing is to not get slow and I blame this on an
inexperienced tuggie who strives for a good climb rate at the expense of
the glider.

Sounds to me that this method of staying low in ground effect for low tow position will increase the time we spend in the dangerous zone below 200 feet, in addition to transitioning through the wake while low and slow. Personally I prefer to spend as less time as possible down low, and would rather transition to low tow position at safe altitude and safe speed. Especially at high density altitude such as we have in the west, fully ballasted combined with not so powerful towplane, the last thing I would want is to purposely stay in ground effect at the end of the runway while the tow plane slowly climbs higher. I never tried this, so maybe it is not as bad as i think it is.

One reason I will never do this in a ballasted glider is wind shear.

Low tow increases the glider pilot's vulnerability to a slow tow.

If excessively low on tow wind shear can be a factor. Properly flown, my experience is that it is not.
Possibly you can explain your second contention. Slow is slow no matter which position you are in.

I received my glider training in Minden. Some of you might have heard rotor can be a real thing there. From day one I was conditioned, if I ever lost sight of tow plane to release immediately, and I have! Other than training the only low tow I have been in was back in the 90's we (local not Minden) had a string of very poorly (not) trained tow pilots. It was so bad pilots were making signs that said "Fast tow". To this day there are no radios in the local tugs I was flying a loaded ASW-24 and was so slow and low that the tow rope was basically just inched in front of the leading edge (CG Hook). Thank goodness for the Nixon/Murray water system, dumps fast. Since this tow pilot was towing away from field low and slow, I to wait until I thought I could make it back to airport before I released. On the ground I spoke to the tuggie. He had no clue gliders carried water ballast. I held up a sign that said I had water ballast before the tow he thought that was drinking water! That same day he towed a 1-26 at 70 knots straight away from airport with no mind of return to airport for the 1-26 driver. Since I got back into gliding our tow pilots are some of the best pilots of anything I have ever met! Perhaps all this boils down to improper initial training. If I was sleeping, dreaming of being on tow, and in the dream lost sight of tow plane, I would still be pulling for that release. Of course I don't mess with anything else on tow because I have been trained while flying tow, that is the only thing you should be doing!

In Minden before each training session we briefed the tow and we briefed immediate release if lost sight. It was much more than cursory, or something we mentioned a few times, it was part of every before flight emergency procedure spoken outloud.
