This is my first contribution to surfmatters and I'd like to endorse the Jet Fins as my all time favorite mat surfing fin. Born in the 1960's they work great. I use them for scuba diving as well.
On Saturday I was out at Far Rockaway NY, weaving my way through crowds on my K-mat. It had been a while since I've been out due to injury and ailments and it was so refreshing to be back out. The fins got me into the sloppy occasional 2-3 foot waves with ease. Almost effortless, it was a sweet simple session.
Hope you are all kickin' it in some nice swell.
ps My fin quiver consists of churchill's, da fins, rip force fins and the above.
