Yeah, I’m with you on the twin fins and keels. Love the freedom that comes with twin fins and especially keels. That extra drive and speed is just an amazing feeling.
I got into surfing as an adult and mostly surfed longboard before heading down in size (mostly so I could surf the right board depending on the days waves) but thrusters always felt a little constrictive to me. Felt like I was tied to the pocket and needing to pump to generate speed felt like work I didn’t really want to be doing. My feelings on thrusters is almost certainly more due to my lack of skill than anything else.
But with twin fins, especially keels, I felt like I could be on anywhere on the wave I want to be and still have the speed to get back to the pocket. I’m more of a flowy surfer not so much power surfing so twins just feel so buttery and smooth.
