That's a really interesting take on that. I will probably keep it original, mostly because I'd want to get an understanding of the original before changing anything and would probably want to pass on an original to the next owner. But I can appreciate that, and it's maybe something to think about if there is any kind of tragic damage to the fin or box. Did Greenough use volan for his fins? What's the specific material used for non volan fins? I never really thought about it before outside of differentiating between "regular fin" vs "volan fin".
