Vanish is my secret ice weapon. Both the 2 and the 4 pound variety pending target species. Three reasons really. 1. Fluorocarbon does not stretch. 2. Fluorocarbon does not absorb water. 3. Strength and limpness are exceptional.
Line issues I had in the past were largely in part a product of a spinning reel and not the line per say. The retrieval action of a spinning reel will twist the line as it is being re-spooled. This action is enhanced and accelerated if you do not have your drag set right when fighting a bigger fish. Should never retrieve with a spinning reel when a fish is pulling drag no matter what type of line you are spooled with, yet it’s a difficult to resist when in the heat of battle.
With that said ~ yes, you can get bad spools of anything (out of box) that never seem to lose the factory memory.
You also have to take into consideration your choice of presentation with your choice of line. For example, not exactly an ideal setup to fish a 1/8oz slender spool with 2 lb mono. Or a #16 gill pill with a heavy braid.
I used to re-spool spinning reels two or three times in a 3 month ice season in my neck. I was quick to blame the line and went through a variety of brands and type of lines.
Four years ago I bought a fly reel as a result of the all the hype. They were the new buzz in ice fishing. A cheap $20 Cahill. I have since converted all my ice rods to fly reels. Line retrieval does not involve any twisting/rolling action off a fly reel. Straight on. Straight off. I spool new line at the beginning of each season now. And it’s a personal choice….Not a must because the line looks like a long lost relative of the original slinky.
I have had no issues with line twist and don’t need to worry about presentations acting like rotating helicopter blades.
