Is any one better than the others or are they all pretty much the same?
I might have company in my little tent tomorrow, so if I want a second line on the go I'll need to do the tip-up thing (I prefer to be able to keep an eye on both lines) but I currently don't have a tip up, and I figure for as cold as it's going to be tomorrow it would be nice to have one that will help prevent the hole from immediately icing over.
