Are people running the same size fins for a paddle board and surfboard?
E.g. large fins being used for both Boards?
I do.
I even often use smaller fins, especially the rears, on SUPs. Typically L in front and M in rear(s) for the Quobbas.
On a shortboard, your rear foot is on the fin, pushing on them.
On a SUP, you have a longer rail line, and more swing weight, so a bit more looseness in the fins is useful, if the waves are not too big.
I guess if your SUP has thick rails, you may want bigger fins to avoid spinning out. But bigger fins slow you down, and speed is very useful to keep a SUP nimble.
Quobba are more efficient than other fins, so the water flow around them both creates less drag, and more hold.
I invite you to read their testimony pages, they ring true once you try them.
I put the link since I see the reorganized the site and are now hard to find:
