Working on a disarm/trip/reposition build

[Railak]

So I'm working on a disarm trip and reposition build using a grapple hook using the hook fighter feat. System is Pathfinder, class is fighter, race is human.
I have the first 11 levels figured out
whip proficiency
hook fighter
combat expertise
improved trip
greater trip
fury's fall
improved disarm
greater disarm
improved reposition
greater reposition
quick reposition
tactical reposition
and weapon focus (grapple hook)
these feats are not in the order they are taken

Im drawing a blank on the other feats to take after level 11 to increase the build. The character isn't really meant to do a whole lot of damage.

So much for the classic Weapon Specialization!

Maybe add some dirty fighting?

Dirty Fighting? that combat maneuver thing? I haven't actually looked into it, guess I could xD

Doesn't seem too bad, though either of have to move things around, or take it late.

Otherwise if anyone has any feat or second class suggestions. Depending on the class I might just rework some stuff for it. I looked in Path of War, I don't know if any of them is really what I'm looking for. Zealot has some useful abilities, so does warlord. But no abilities that really add to trip or disarm.
