I like to use 3wts on beaver ponds and swamps, the 5wt seems too spook the fish a little more. a few weeks ago i was fishing a pond, there was a nice fish rising but there were floating logs that got in the way, so i got on a point about 80 feet away, wasn't able to reach it. And the reason i think my 3wt is more accurate is just the rod fits my casting style better, its my favorite rod and i have the best feel for it. i have it longer than my 5wt and use it whenever i can. I just use the 5wt on lakes where i commonly need a 70 foot cast.
