Great set of fins
I am not an experienced surfer by no means. Started surfing in Sweden in my early twenties, moved to Australia and have been surfing ever since, now 50yrs old. I am not good enough to evaluate that set of fins to those set of fins but when I tried the H4 I did notice a difference in my speed and drive through bottom turns and top turns. My all rounder board is a JS MonstaBox 2020 6.0 32L which I surf in anything from 3ft to 5ft around the Northern beaches in Sydney. Have a trip to Bali in July and a Mentawais trip in October booked, can't wait to test the H4 in some decent waves.
