I nixed my auto fly reel, doesn't hold enough throwline for my purposes. I carry 150 ft. of the 1.75 ZingIt, sometimes I need that length to set a traverse or to make a pulldown for a high cinched SRT pitch. Also I like be able to use both ends of the throwline if needed.
What I do is pile a handful of loops in the palm of my hand then stuff it in a little bag, repeat until line is taken up, goes quick. The way it works is that any tangle is isolated to one handful of loops and if the tangle happens it falls apart with a shake. I have a mini biner with a 6oz and an 8oz bag (tied to throwline) that also attaches the storage bag to my harness. When I'm climbing the biner with throwbags hangs inside the closed throwline storage bag, when I'm using the throwline the biner and extra throwbag hang outside the storage bag. If that makes sense.
