Some general questions on campagnolo 10 speed compact chainrings for a Centaur square taper.

Are all Campy 10 speed compact chainrings the exact same bolt pattern

Any advantage to the AFT chainrings?

Do I need to find ones that have ud and eps?


Does it make sense to use TA or some other brand will shifting suffer?


Do I need to replace chain ring bolts at the same time?

Do 11 speed chainrings work or will shifting degrade?

Thanks
