Tusa zoom3, mares quattro and aqualung slingshot fin comparison

hi, this is a quick...straight out the water comparison of 3 of the best fins on the market! I filmed this down at Porthkerris , Cornwall on a beautiful sunny day, sadly viz was poor as a consequence of a bloom, but that resulted in basking sharks and a pilot whale being there today....swings and roundabouts!!!! I personally did not like the Tusa fins...you feel like you are not getting anywhere, and as a result I can see it reduces the risk of cramp....but frankly i like power incase of strong currents or emergencies. I did not try the slingshots, but I am told they are excellent and the power from them is controllable via altering the tension in the rubber spings. My favourite is the quattros...I think they are bullet proof and i love the clip systems...much prefer them to springs. I would love to try the newish Mares x-sream fins...they have the buckles...and are nice and lite. (so if anyone from Mares is reading this...send me a pair lol and i will do a review!)
