schwatz the difference???

...I'll tell you what is schwuz. On the left you have a single-foiled quad trailer fin (flat inside) which provides lots of drive and hold, better suited for point type waves. On the right you have a double-foiled quad trailer fin (curved inside and outside of fin) which will have less drive than its counterpart, but will allow quicker and more fluid turn initiation (more responsive) and is more suitable for beach break conditions. Stay tuned for more info...
