Eddie, Neither can I, but they are not meant to replace bigger rods, but try using a 13' to 15' rod on a small to medium sized river, then try a switch rod and it's then that their flexibility comes into its own. They are called switch rods because you can switch from a single handed cast to a 2 handed cast, you wouldn't try casting a 15' rod single handed would you. They are also built to use lighter lines than a 13 to 15' rod, on average a 5 to 8 weight, if you want to have a short rod to throw a heavier line then your getting into skagit territory.
