My first fins when I started training were Mares Quattros. They were good but I found my legs tired quite quickly, unexpected as I'm a regular runner. It was like cycling stuck in too high a gear. I swapped to Apeks jet fins that were about 6" shorter and was instantly a lot more comfortable. Also the spring straps are a lot more robust. And yes I use high-density RK3s for twin set where there is more weight up the body. I find the neutral RK3s perfect for everything else, from single aluminum backmount in a shortie to twin steels sidemount in drysuit. But there were no videos around at the time so I had to find out for myself. I'm sure this video will help a lot of people.
very informative with information not easily found surfing the web. Many thanks.
