I don't have the rubber hoses yet, other than what's on there now for the drums. Was actually considering the braided lines. They didn't mention any of the potential issues with fittings.
After looking around a bit I was just thinking about maybe going with a full set of stock lines and hoses then getting an adapter at the MC (if I even need it) for the front MC to brass T line. That way everything matches up for sure. Worst case I have to bend the pre bent stuff a bit to get it to line up with the outlets on the proportioning valve.
Where did you put your residual valves?
