Where I fly only low position aerotows are performed and even in turbulent conditions with glass gliders, rope slack doesn't seem to be much of a problem.

Are high position aerotows more prone to developing rope slack?

I flew in low tow in South Africa for many years and clearly remember a few instances of very slack rope. One time the tow plane flew into a strong thermal and slowed so fast that the tow rope snaked back over my canopy and far down the fuselage. This was in a Jantar-1 that had the hook under the front belly.

I was taught the offset and yaw recovery method rather than the dive and hope-for-the-best method and I use it fairly often in our strong summer conditions. I am much more scared of simulated rope breaks below 200-feet!
