High speed 500 fps and 200 fps filming of 3 elite caster including Jason Borger showed that maximum tip speed was about 53 mph when casting 10 meters of fly line plus leader using 9 ft 5 wt fly rods. Rods were a Sage TCR, a T&T Paradigm, a Sage XP, and an Orvis Zero-G Tip Flex rod. All of the casting was performed indoors to eliminate environmental factors such as wind.
