Fuego tail shape

Someone can explain me the main feeling difference regarding tail on El fuego surboard, swallow or diamond?

Hey satan,
So think of it this way:

Swallow: a little more bite and greater control at higher speed
Diamond: a bit smoother from rail to rail and slightly more lift in the tail making it a touch better in smaller surf.

The differences aren't major though and are more noticeable for those with more experience surfing.
