SZD59 compared to Fox and Swift

[Some]

Dear all,
I consider to buy a SZD59 for aerobatic purpose.

I would like to hear opinions from people how knows the glider. How
well does it perform compared to Fox and Swift? Is there figurs which
are especially difficult to achive in this glider? How well does it
handle in positive/negative flicks on vertical axis?

I'll appreciate any comment regarding this matter.

Best regards
