So, I have my trusty steel steed cross bike that I want to move to campy potenza. From shimano. I have two compatibility concerns.

1) I am using shimano's cx70 top pull road FD as I despise pulleys. Has anybody tried the potenza stuff with that?

2) This frame has IS disc tabs. I am currently using trp a spyre calipers and good use those for the campy build too, but I am wondering if I could get away with using magura calipers with the campy levers. I know the fluid will play well, but am worried about the specifics of fluid volumes and flow between the two. Has anybody dug into this?
