hi brad
earlier this year i was lucky enough to have a bit of a play with RF78xh
i found it was the strongest rod in there range by a long way, it is quite light
to use and could cast it all day without needing a chiro. only loaded up on a fish
for a brief moment but it felt pretty good.
i was only casting 150 cuberas and i think that would be the minimum you would want to
use with this rod
hope this helps brad
cheers john
