Answer
Dennis ,
If you got your rod in a kit with  spool of backing , put all the backing on the reel , unless it is a small reel.I think that is 140 feet of backing.  Many fly fishermen don't use backing. Backing is used  when a big fish takes all 30-50 yards of your fly line out. Buy a tapered leader at a fly shop, try a 9 footer 5x  and get a spool of  tippet 5x , too. But don't be afraid to talk to the guys at your local fly shop they are usually very helpful .
You are welcome
