McDing nailed it.
In Oceanside Ca., with no less than 20 glass shops(mine included),
Future Fins and FCS fins dominate.
Probox is used very seldom. Lok Box too.
Years ago, Swivel Fin System came along.
You could adjust Toe, Cant and could adjust fins forward and back.
Problem was, fins were all out of whack. No-one could adjust the fins properly. Only industry pros could. Because the average Joe does not have jigs to properly set them.
Great idea if you have the tools and know-how to adjust them.
If not, you could take a great board and ruin it with not only the wrong fins, But put them in the entirely wrong positions.
4WFS does have many options. If put in the hands of someone knowledgeable.
Personally. I prefer to glass over the fin system. Just plain stronger.
Cutting a hole after the glass job and putting in a fin system seems a bit archaic.
Which is why FCS went Pre-Glass also.
4WFS system seems the way to go put in the arms of someone who knows how to adjust fins.
I prefer Future.
Not promoting any one fin system. Larry has a great fin system and fins.
Just stating the industry standard.
