I have a DG-101 with conventional tail and one piece canopy. I can say that aerotow with the CG hook has been a total non-issue for me so far. Takeoffs are easy, just remember to follow the flight manual’s guidance. I mine, the trim should be set full forward for takeoff. I don’t know if this is true for the -100.

I have found the -101 to be a docile and responsive glider with very gentle and forgiving stall characteristics.

The airbrakes are only moderately effective, however.
