    So, I am new to spey fishing and I'm getting all geared up with a 7WT. I want to put an Abel Super 10 on it because that's the most suitable reel I've got on hand. I'm going to use a Skagit short. I've got all the mow tips, the line, the running line and now I'm thinking about which backing I should go with. Having only fished 2 handed one time and didn't hook anything I can only assume that seeing your backing when you hook a fish is pretty common. Is 20 lb. enough or should I go with 30 considering that it's a large arbor Super 10?

    I'm thinking that this will be primarily a winter use set up, but I might want to swap line off of it and use it in the summer.

    If you ever plan on using it for Kings, use 30#.

    Yep, 30#. You have plenty of room on your reel to put 150-200 yards of 30# with the line your using, which is plenty of backing.

    Benjy,

    20 is enough, but if the reel has a large capacity 30 is convenient to avoid having to wind on 300 or 400 yd. I have 20 on all my reels I use on single hand rods, and 20 or 30 on the reels that go on two handed rods, depending what I had laying around.

    20 will be ok, but if you fish for kings or chums, Id use 30

    20 is probably 10 to 15 pounds lighter than the breaking strength of a quality 7 wt line. Your call. I never use anything buy #30 or higher.

    20# for most situations would be fine. but you risk looking your entire line if something went wrong.

    30 for winter type fast water and big fish. 20 for summer situations. If you only have one reel go 30.

    The first question is 'what is the internal core strength of the fly line you're going to be using. The backing should be at least that amount, or more. Personally, anything over a 6wt line will get at least 30# backing.

    Funny that for decades I used single hand rods and reels sized to match that were universally loaded with 20# backing. Must be a good thing that I didn't realize what I was risking. Without fishing for them on purpose, I caught kings and chums (one summer king on a fiberglass 7 wt, a combination I don't recommend) without ever losing any backing or flylines. I did lose a number of flies due to deliberately breaking the 8# Maxima leader because they weren't the species I was fishing for.

    I load Spey reels with 30# dacron, not because I think I need it, but because it takes a mile of 20# to fill a big Spey reel. If you're fishing 20# leaders, I suppose there is an increased risk of losing one's fly line tho.

    Sg, it doesn't take 20# leaders to do it. I would not use 15# maxima with 20# running line. For me it is abrasion if the backing hits rock. The 30# is much better at that.

    DocDoc,

    I guess I believe in calculated risks. What are the odds of the 20# backing hitting a rock and abrading enough to break? It's never happened to me, so I expect it will when I hook a world record something or other. But since I don't care about world records, I've nothing to worry about.

    Phil,

    Of course Maxima is thicker and stiffer than other mono brands, and possibly no stronger on a diameter for diameter basis, but after 3, going on 4 decades of using it, it's never disappointed. Not something I can say about other mono brands, altho I'm open to comparisons.
