I am returning to speed sailing after almost 10yrs and am sorting through some bits n pieces. I have a mint Mal Wright 'Time Machine' asymmetrical carbon fin (Mk2 I think) which I bought from Mal himself at a Sandy Point Speed Week around 2005.
While others destroyed their fins, mine stayed in one piece. Back in its day, this 21cm fin was considered small but it seemed to work ok.
Question is... is this still an acceptable fin to use, or is it one that would be be better binned compared to what is available today?

*Only white because of a painted finish.
