John C's comments are well said.

A few extra thoughts of my own.

"crow hops" (near heard that term before but I get it) might equate to a "high speed taxi" which is how the general aviation (GA) powered crowd might take a few hops off the runway to test the new hardware. This might work for self powered aircraft but not for a (non-powered) glider.

Think about a glider on a tow rope behind a tow plane. Having the tow plane pull you to take off speed, then you come back down and both you and the tow plane need to come to a halt in unison. The take off is the trickiest thing to master anyway, these hops you suggest would be REALLY tricky.

Of course there is this aspect of the first flight in a single place glider which very few powered GA pilots have ever experienced. Nearly all of them have flown with someone else in a 2 place before soloing it. Even a single place Pitts has a two place equivalent. The point is that gliders are different beasts with special needs. I don't mean to scare, just to get specialized training.

So, anyway, the common course of action is to take a high tow (5,000 ft AGL) early or late in the day, while pretending to execute landing patterns multiple times as you descend. That and a good briefing of the ship beforehand by the POH and an instructor you trust. Especially if this glider of yours is a CG hook and you have never flown one before.

Good luck and stay safe.
