I love press/fb and with potential it has made it one of the best sets, imo. You can easily get a team of 80ath/80 speed guys in div III and div II and just run teams off the court. Find the 40/40 players with high pot in both and just solid enough cores.
Now, press/motion seems to be the top combo. Mainly press, but motion seems to be most used with triangle 2nd and then flex.
