Gear: The Future of Fly Rods?

Could your next fly rod be in the shape of a triangle? The Angling times says it just might be:

This unique property is the result of Chris having based his design on the fact that an equal-sided triangle has more integral strength than a circle, a factor incorporated into the unique ‘extended Reuleaux’ shape of D-Flex’s cross section.
“I first developed the idea when learning to Spey cast while salmon fishing a few years ago,” explained Chris, whose 30-year career has been spent designing artificial blood vessels.
“A triangle isn’t practical for rolling rod blanks, but the shape I have come up with - a unique piece of geometry called a curve of constant width - is perfect for fishing rod manufacture,” he claimed.
