I am considering the Prana fins by Cetma Composites and have the option of getting them with either glued foot pockets or screwed that detach for easier transportation. I know that glued foot pockets extend the durability of the blade but I'm trying to figure out just how big a difference it makes and if there are any other advantages or disadvantages to consider. If I opt for screwed foot pockets I think the fins will just barely fit in my bag that I always take as a carry on. With glued foot pockets I think I would have to carry my fins separately which would be quite inconvenient. Any insights are greatly appreciated, thank you.
