AF-4500 , 300XL, AP

Course interception using the 300XL directly works very well with the AP however using the FD I have wild overshoots coming onto a heading. Because the 300XL is intercepting so well out of the box I presume the internal AP settings are pretty good.

Can anyone share what FD settings seemed to work the best for them in a RV7?
The only complaint is coming into an existing track from a large angle. Is Roll GAIN the only adjustment or is there something else for course interception?

Once on track both FD and 300XL are amazing!
