I think you can't really ask this question without also discussing storage. The same line performs totally different on a hand real than it does in a throwcube. For my money, I use he 2.2 mm zing it. Mostly out of a thowcube, but we have a couple shorter zing it's on hand reels that we use for pulling sections around.
One thing that makes a big difference is I twisting the line when it's new. When over a new roll of line, i go to the park and in reel the whole thing, then take it for a walk. I know another guy who takes his fishing and trolls it behind the boat. He swears by it. You only do it once, before putting the line into action.
I like the way the 2.2 zing it handles. On the hand reels it does tend to get more
Twisted though.
