GOOD WING SAFE FOR ACRO

I practise acro under an APSEN GRADIENT 24 (I love this wing) and I'm not a super pilot but I can do Helico, mysti, sat assymetrik, loop and full stall. and I'm looking forward for a new glider that is also easy in acro like my Aspen because I still do mistakes (especially in helico :-))). I tried the Dune XS but i Didn't like it it at all...too speed, just didn't feel good under. I love the Aspen but it's a too light conception not really strong for acro and mine is getting old so i was looking for the new cayenne2 or the summit 3 ? or something else. Does anyone can advise me?
