I have been wanting to try a character that utilizes tripping with Vicious Stomp and Greater Trip for a while, and I started playing a Brawler in Pathfinder Society with this build in mind. I hit 2 in a recent session, so I now have access to Brawler's Flurry. My feats so far are:
Bonus: Improved Unarmed Strike
Human: Dirty Fighting
1st: Improved Trip
2nd: Combat Reflexes
I'm set up to use Martial Flexibility to gain Vicious Stomp during combat now, but I'm not sure when the AoO from it would take place when I am flurrying. I want to trip as my first attack while flurrying to make sure I down my target and that they're prone for my later attacks, along with dropping their chance to hit or forcing them to stand and provoke strikes on their turn. This way if I miss the first trip I can also try again using the second flurry attack. If I flurry and get a successful trip to start, do I finish the full attack first and then take the AoO from vicious stomp, or does it happen in between my flurry attacks?
Would it be:
Trip vs CMD (flurry attack 1, -2 penalty to hit) - success
Attack vs AC -4 for prone (flurry attack 2, -2 penalty to hit)
Attack vs AC -4 for prone (AoO, full attack bonus)
Or would the AoO happen between the flurry attacks, forcing any later ones to resolve afterward? The AoO will not suffer the -2 penalty from brawler's flurry, so I want to make sure I add my rolls correctly.
