I can’t speak for the 45lb but all I run is AFW 30lb copper and I have had zero issues.
It’s not nearly as stiff as Bloodrun and have had very few kinks and never a break off.
You can fit 300’ of 30lb copper ,800’ of 50lb braid and 40’ of leader all on a 50 size reel. Have reached 80’ down with a little backing out trolling mag spoons.
