Hi Will,
I'd regard the Aries 07 as a "nice" plane to fly. It's (mine's) not mix free.
It also tends to have a habit of going off line quickly in a manoeuvre if you start out a bit offline.

From an F3A perspective it's about 3 generations out of date and you're going to struggle with any maneuverer that requires high G levels of knife-edge performance. It's snap roll performance has never been crisp either.
I tend to just sport fly it now, which for me is mainly the pattern schedules of the era without the snap rolls or spins and flown in a bit tighter occasionally throwing in some of the newer knife edge stuff modified to remove the really high G knife edge components.
Just generally convincing those in the pits that it must be less windy up there, than they're feeling on the ground

The DZ200CDI with 21.5x10.5 prop has improved vertical and downline braking compared to the 170CDI but this was an airframe designed around a 17x13 - 18x11 (I was running 19x11) and the bigger prop does make it's presence felt at time..
