Cutting down 70 cm fin to 55 or 62 cm
I need more fins for my X-186. I have a chance to buy a stock 70 cm fin in near-new condition for about half the price of a new fin. How awful or functional are the results likely to be if I cut down the 70 cm fin to a 55 cm size or to a 62 cm size?
My only other Deep Tuttle fins are a 70 cm pointer fin and a 40 cm cleaver fin.
I'm not identifying the fin manufacturer because I don't want the answers to be about the general merits of the manufacturer.
Thanks for your input.
