I've been looking to buy some carbon fins. I don't want to buy something that is likely to break. I've been thinking of Moana Watermans, Deep apneas, Mako carbons, or one of the C4 fins. I've been leaning toward the Moanas because I watched them be stabbed and they don't seem to buckle, but my opinion could be easily swayed with personal use. What would be my best bet? I do spearfish as well.
