The Futures EA fin is my Go-To fin when I want to lay down rail turns at speed. These fins do still offer ample release off the top. When you want to stay on rail (when paired with a step-up or high performance shortboard) they won't slide out.
I typically use these fins in my 6'2" Ghost when it gets bigger and starts throwing but also in my 5'8" Dominator 2 and Sub-Driver 2.0 when its weaker and mushy but still has an open face or when you need to get down the line fast. These fins can be a great choice if you can't decide which fins to take on your trip, use at home when its pumping, or to keep in your board bag as a backup to your small wave fin.
This is a set up that I always keep close by.
(The Tech-Flex option is better as an everyday fin while the traditional fiber glass option is stiffer and will offer better performance in even bigger waves of consequence).
