there's no reason to suffer bad line.
I remember as a teenager, my dad fishing 808s w/ 25-lb mono inshore, while I fished my Mitchell 300 (with the added torpedo-grip long handle), 14-lb Stren and 7' Tri-sport, and caught all the fish.
When I grew up, began buying him Lew's and Falcon rods for birthdays and Christmas.
My girls started on Zebco UL-1 with Eagle Claw Featherlight, the reel loaded with sexy 4-lb copolymer.
Those long fishing trips with my dad always need an afternoon tuning his tackle, and usually replacing a working portion of his line on at least one reel - most always replacing that working portion of some cheap chartreuse gawdawful 25-lb mono with 12-lb Seaguar. I always bring my bulk spools, and it's kinda funny, he always makes fun of the amount of gear I bring.
(this is doubling the leader length on his popping cork, and may have been an excuse to sit on the palapa with brew and stogie)
He will then lube his reel, we'll find where his casting brake is really set, and re-set it properly.
to me, massive line test is the equivalent of a bad chef. Both my dad and Stevo migrate straight to this practice (though Steve is a phenomenal chef), but the bad chef analogy - if 15-lb braid is good, 45-lb braid is better (equate to spices).
But they're the only two people I know who carry spare rod tip-tops in their tackle - and use them.
