Fast Bobby is a wing foiler who wanted to compare foil wings across brands. Every manufacturer publishes sizes in its own units and on its own measurement basis — so he built the comparison.
The site is 1,015 wings from 23 brands, converted into units that mean the same thing everywhere. All but 38 of those figures are a manufacturer's published claim, converted — and the exceptions say on their own page which retailer or review they came from instead.
Each number points at the page it was read from. The method page sets out the sourcing rule, counts the wings that currently break it, names them by brand, and explains the straw underline.
Corrections are welcome, especially specific ones: contact.
