From FW USX motion to Wrist DBX motion

Over the past year I tried to become a FW player to unlock my DWPS/USX potential. I was able to unlock some great things but after joining the site I wanted to slowly transition to a more neutral PS and using wrist motion. In the clip I do the same Asato lick twice with my FW motion and twice with wrist motion. Im trying to break through the speed barrier and get this lick to its real tempo at 160bpm. What are ways I can improve and which form is best for it?
