I recommend to see the full sessions. The highlights video are too edited to be useful.

What I found interesting in this 7h30 long video was:
- as usual, seeing how they get back to the lineup, manage chop, keep their balance, survive the foam walls, ...
- the different kind of boards used. Most boards are similar (pulled in nose, narrow, round pin tail), they are designed for vertical surfing (pivot more than drive) but they differ in volume quite a bit. They ride boards nearly 1' longer at Sunset than the other venues (8' vs 7'4"), and of course most are custom designs, not production (the absence of a handle is telling).
- what was new was Fisher Grant using a mini-mal step railed shape(*) (Portal Phantom), interesting choice, much stabler and more glide than the others.
- The masters (50+ years) at 5h07' were on more "normal" boards (bigger), interesting to see

The video of the day before was survival more than surfing, but one heat was interesting. At 1h01, the round 3 heat 3, sported 3 surfers with quite different styles: James Casey was surfing horizontally (speed, drive, cutbacks), Luis Diniz was surfing vertically (tight pivot, in the lip), and Fisher Grant was on his mini-mal with different curves:
