Hmmmm.......not sure I'm with you Jax on line change applications being mostly unneeded.

I can think of tons of applications where I routinely change my lb test.

Finesse presentations with a j-11 rapala or a slider and 4lb xt come to mind.

How about a chatterbait in the weeds.........better have 10 or 12#

8# for topwater smallmouths

6# for trolling deep cranks (yea, I know I'm daring.... The 9' steelie rod lets me get away with it)

And then of course I never hit canoe country without a selection of big baits. Baits pushin 9" require 15 or 20# test just to be able to toss without breaking them off on the cast itself.

If I'm in the Q and it's a fishing trip more than a travel trip I will have on hand 4, 6, 8, 10 and 17 lb test. Two identical spinning reels with 2 spools each and 1 baitcaster to handle the big stuff.

Of course each trip is different. This summers WCPP trip is a travel trip and although I intend on running a line as often as possible (weather permitting) I don't want to get bogged down playing fish on to light of tackle. So I will likely "up" my line test considerably to make the battles a bit more of a down and dirty slugfest than what might be otherwise.
