My "worth what you paid for it" opinion:

You are overthinking the problem. This is a known design with no unusual characteristics. Take a high tow, get the feel of the controls, do some practice approaches, feel the changes when you open and close the spoilers, etc.. By that time you will know how it flies - then land it.

Crow hops are not usually done anymore for a reason - they are not necessary for normal aircraft. And I can think of several ways for things to go wrong with a relatively high performace glider (it's not a primary!) at low altitude when you are concentrating on doing a lot in a short time. Wrong place to be if something distracts you, etc... Think about it. Get away from the ground so you have the options of sorting things out.

Crow hops for testing a new design or for no-instructor primary training is a completely different thing.
