Well ... Yes and no.
It depends on everyone... For my part, the only casting rod that I carry with me (almost always) is the BassCaster and the other 6 spaces I use with match and spinning rods, from a light setup to XHeavy setup.
However, I usually plan my trips carefully... With schedules, fish species, lures or baits and the necessary setups.
Then I spend several days in that locality until I achieve what I went to capture (Uni fishes or just fishing for farming money) or until I get bored.
Obviously everyone have preferred setups to carry (Zeus and Brutus are inmovable, so only 5 left) BassCaster, Fenix, Thora, Aurora, JigWinner are good all round rods... And the others are most specific when your looking for a certain size or fish species ( lure and line weight and cast distance are determinable)
Good fishing and tight lines!
