With a 3 wt I think you (or anyones) longest cast is goning to be like 10-20 ft
Good to know I've got the greatest 3wt ever! Or maybe I didn't get the memo that you can't double haul with a 3wt. Just gotta figure out how to get the poppers to kick over at 70' with the 3wt.
I would say anything over 40' is durn fine for a 3wt.
