For less stability, and more manoeuvrability?
Please don't use "less" "more" stability - it's meaningless without additional qualifiers.
Aft CG gives lower apparent static stability, lower manoeuver stability, generally less well damped short period longitudinal and lateral/directional static modes and Dutch Roll mode, it may well make the long period longitudinal mode better damped; the spiral mode is more complex because that is primarily dependent upon the RATIO of static lateral to directional stability.
It's the lower static and manoeuver stability values that tend to favour aerobatics, the reduced damping on the DR can be a nuisance, and the reduced SPO damping can interfere with accurate pitch control however.
A lot of that is trade jargon which most pilots don't need to know - but my important point is that to say something is "more" or "less" stable is generally over-simplistic and potentially misleading.
