i made a hi-vis level furled line about 27' long and put a 4' tippit on it. i was casting using the Fountainhead Caddis 330.
it was a little tricky to get the line up in the air to start, but it actually cast very, very nicely.
(un)fortunately, i didn't get any strikes during my experiment. i am curious to see how i could handle hand-lining 30+ feet of line in with a fish on it.
what the limit of what you try to cast with your tenkara rods?
