Basic glider aerobatics is most commonly taught in the K21 due to availability here. And sometimes in the DG1000. You are right in that the rolling maneuvers are more difficult in these. Simple maneuvers as loops are easy. And all aerobatic gliders are very slippery so overspeed is much more of a risk than in most powered aerobatic planes. The best 2 seater aerobatic glider presently is the Fox, but those are scarce. I believe there is only one privately owned in the whole of Scandinavia presently. All other 2 seaters have limitations on allowed maneuvers.
Takes a bit to learn turns inverted. Inverted turn requires rudder pedal the direction you want to turn but opposite stick. Sounds weird but makes sense when you think about it. Expect dirt to end up on your hair.
Yes, takes a bit getting used to and in gliders the much stronger adverse yaw inverted also takes some geting used to. Regarding the top rudder in turns it initially helps to think left or right foot and push towards the sky to hold the nose in the correct attitude. Thinking like this is also useful in spins in order to not confuse left and right. But lots of fun...

Aerobatics in a heavy two-seater must be hard work.
Definitely not for the faint hearted.
ASK21 is rated for aerobatics. +6.5 Gs -4.0 Gs.
