I've tried a range of custom FFB files with three different wheelbases, including my current Fanatec Podium DD1... and I still have issues with the way PC2 feels. But as we all know, it's a matter of personal taste and I'm perfectly happy for anyone else to enjoy it.
To be honest, PCARS/PC2 became an ongoing frustration for me. I bought into the 'crowd funding' thing with both the original and PC2, spent a lot of time on the forum discussing things during development, and tried to love the result, but AC* pushes my buttons in a much stronger way. So now I just spend my days and nights with this 'mistress' while PCARS deflates in the corner.
(* To be fair, I should really say it's AC with CSP/SOL/Crew Chief/and mutiple other add-ons that pushes my buttons. And I should probably also add that I have no interest in 'game' elements, like flashy UI's with whizzy noises and animated prizes, or 'challenges' and the like. I just want to drive what I want, where I want... and for it to feel as close to authentic as I can get it to.)
