An alternative to TOPCAT for Aerosoft Airbus serie

Hi all, I am currently flying the Aerosoft's Airbus serie IAE engined aircrafts and for a while now, I have decided to became a more sophisticated flight planner as well. The first thing I've done was to install PFPX and in time I learned quite a lot from it. It gives me pleasure to use it but I cannot use TOPCAT with PFPX, (I did not even buy it) since it doesn't support any Aerosoft aircraft. So I wonder if you have some advices of any alternatives to TOPCAT. Also there is a performance sheet printing feature in the aerosoft's Airbus as well and I cannot be sure if such an add-on is really necessary for realism. I am waiting for your advices.

Best regards,

Enis
