So all the folk on here who have been early adopters, who have been generous enough to share their experiences, have made something that seemed out of reach, more doable. The only way to find out why all these really handy SUPers were converting to foil was to do this.
Thanks to everyone for the inspiration, Tom for his foamy wisdom and Matt at the SUP hut for an invaluable foil clinic and couple of sessions on the overhead cable.
All ready to tumble.
