I have been using the Kalohe Andino large fins for a while and they are a tad bit faster than the channel islands large thruster fins. However the Andinos are a little to jittery for my 5.10 18.60 2.33 27Liter high tail rockered shortboard based off the lost whiplash. I am 150 by 5.10. The Kalohe Andinos also stick a little to much for me when I'm up in the lip on less vertical waves. The Channel islands fin releases easier for me and works better my progressive Surfing style such as nose pick reverses and rotational moves requiring you to break the fins free from the lip to initiate a spin.
