BP do you live somewhere outside of the internet?
No not "Pipefins" just custom polyester fins - very good quality, any size / style you want. I'm not a dealer or anything - just know the guy who is a local fin-making legend... Dont have to buy brand-name fins - just draw a template of what you want & hey-presto it's made for half the price of the brand-name fins.
I make the odd thing or two myself... Recently I've recycled some massive old windsurf fins - cut them down & reshaped them - Got a favourite fin by doing that and it works well, good to give old junk a new lease of life ay
