What fins are you using in your surf SUPs at the moment. Pics would be good

I'm using GL quads in my Lopez 8.10
The standard Naish fin in my 10.6 Nalu (I think its 9 inches) with a set od glass m5s in the sides.
And these Sunova fins in the Skate. A quick measure puts them at 5.25 inches base and 5.25 inches depth.
