I’m similar weight. I went from Med to Lrg a couple years ago. I tend to loosely go down in fin size as the boards’ tail gets narrower. Groveler/ avg wave boars with a wider tail: large fins. Stepup / roundpins: Med fins. Seems to work well for me.
When I (rarely these days) do ride a pointy nose squash thruster, I like Lrg JJF sides, and a Med JJF center.
