You've already been given good advice by others.
If you are serious about aerobatics then forget about the 152. It doesn't even have the saving grace of being economical if you are paying £230 per hr (not cheap) and then getting only ½ an hour aeros for each hour paid.
If all your flying has been with a yoke then it's understandable that the Chipmunk felt strange but that would change very quickly. As Dan says, it's one of the best harmonised light aircraft ever built.
For aerobatics purposes you'll have to switch from yoke to stick sooner or later - the sooner the better.
I agree with Camargue's suggestion. I'd go to the
Tiger Club which now flies from Pent Farm, Postling, near Hythe. An easy 1-1¼ hour drive from Crawley.
It's a well-established sport flying club, founded in the 1950s. I used to be a member when it was at Redhill.
The Tiger Club is owned by its members -
no additional charge for dual.
You'll be surrounded by like-minded people from whom you'll learn about aeros even when you aren't flying, and be able to enter club competitions as you progress.
