I recommend gorkypl get a copy of Jan Heine's book, The All-Road Bike Revolution. There's in-depth explanation of bike handling/steering, including head angle, fork rake, trail, pneumatic trail, and how they all affect road bikes, cyclocross bikes, gravel bikes, and so on. There are even recommendations of various combinations for certain bikes.
Sounds like David Kirk already has a handle on it.
Still, get the book. You won't be disappointed.
