Hey, Bryce!
Man, You did a Tantrum to Fakie
ha but slid back. lol SICK
My first though was to tell you to square up, but you are currently doing that. Another tip I would be looking at telling you is when you initiate the trip on the flip, you are throwing your head on a slight angle out the back. It would help if you concentrate on looking directly behind you...... I used to tell people to look at the shore directly behind their back. This might help you to mot get that last 180.
Cheers,
