haha yeah i had the same feeling but man it made me want to go exercise my arms pretty bad. Ive got one 7ft 6wt and a 9ft 8wt and i reallllly want to get back into tying my own flies again. Btw i think the video was to just showcase casting =P which to be honest im pretty obsessed with perfecting mine XD Not sure if i enjoy the sight of a nice loop zinging out or a fish hitting a dry fly more
