Overview
"A twin fin that you can push harder, turn tighter, and surf more vertically" - Britt Merrick
Bridging the gap between the CI Keel and AM Twin - this high area twin fin provides the drive and hold you expect from a keel, with the pivot and release found in the upright AM twin template.
Placing itself in the middle of the CI family, the BM template has a swept-back long leading edge that leads into a fully rounded tip. Different from other twin templates, this fin is designed to feel secure when laying into a longer turn or driving hard off the bottom.
With the CI Twin Pin/CI Mid in mind, the idea was to help anchor the tail to the wave face so surfers could take a more aggressive approach to ride a twin fin.
Board Types
Performance Glass
Performance Glass (PG) fins are machine cut from 30 layers of solid fibreglass. These fins are stiff and are widely used by pro-level surfers because the integrity of the flex is maintained under immense force, and in the most extreme of conditions and situations.

I bought these for a 6"6' Big Baron.Definatley a lot more stability than the FCS Power Twin in the bigger stuff.
No sliding, can push it a bit harder.
Awesome product highly recommend this item
Nice fins !!!!
My hot wheels
If you have a twin fin that seems too loose and lacks drive, this is the set for you. You get the drive of a keel with the pivot of an “MR” style fin.
