I have recently acquired a Barry Bennett 9'4' x 21.5" old log [mid 60s] that would have had a D fin in it I assume [but I'm not sure]. I'm looking at putting a new fin in it. What would putting a big swoopy fin or a hachett style fin do to it's ridability compared to a D fin? It's in pretty beaten up condition so I'm not over concerned with originality, more concerned with rideability.
cheers
