Default Low towing thought

I did annual checks about a month ago, when we were encouraged to try
low position on the way up for spin checks. I decided that I like low
tow and will use it in future, but before I do so there's one thing I'd
like to ask the Aussies and other habitual low towers: when you release
do you just pull the bung in the low position or do you pop up above the
wake first?

I fly a Libelle, which normally tows with a lot of sag in the rope, even
with the wheel down, and it occurred to me that releasing in the low
position could cause the rings to pass close to the canopy or even hit
it. At least the Libelle has a nose hook: if this is an issue, would it
be even worse with a belly hook?

Proper release procedure for low tow is to release from that position.
How do we know the "right" position? It is just below the tug wake
such that occasionally you will feel the wake on the top of the
vertical tail. Most people not well trained tend to fly too low.
When you release in "proper" position, the rope will go straight
forward and not up over the glider. If it goes up, you were too low.
Tuggie will feel release as in high tow. The difference is that he
will feel no trim change due to glider being on the thrust line of the
tug in low tow.
These comments based on 10,000+ tows at the back end and 5000+ at the
front end in low tow.
