I've changed my practice from carrying a lot of different poles to just carrying one.
But I'll take along a lot of reels with different lines, so I can switch them back and forth onto this one pole.
Crappies? Yup. Got a reel with a line for that.
Bass? Got one for that, too.
Carp? Got one for that. Same one I'll be using for cats and buffaloes, pikes and even sturgeons.
No need to carry bulky stuff.
