I'm definitely calling bull**** on that one Alex; sorry man.
I spent the most part of a fortnight demoing every single board that came within arms reach of me in search of my new board and every single one of them had slightly different characteristics. Some of the character of the board came from the outline, some from the fins, some from the rocker and channeling, but all of them were different.
If you handed me a Nobile 666, and Underground FLX and a Naish Thorn all identical sizes i'd be able to tell you which one i was riding without looking.
Boards make a HUGE difference on the water. I'm a little surprised more people don't pay as much attention to their boards as they do their kites.

If you've got knee problems then definitely opt for the 555 over the 666 or any other stiffer boards. Not quite as much pop or response as the 666 but still a very sweet all round board that's more than capable of taking some abuse.
