A monofilament backing is the best way to prevent braided line from slipping off your spinning reel. When using monofilament, an arbour knot can be tied directly to the spool's aluminium surface because it does not slip.
 

When using electrical tape on a spool arbour, it offers a surface with enough traction to prevent sliding. The final option is a braid ready spinning reel, which has a rough surface designed to improve grip on the spool arbour.
 

In the case of braided line, do you need a backing?
 

Doing so is the best approach to prevent braid from slipping on your spinning reel, as monofilament does not skid at all on the spool's surface. Additionally, because mono is so much less expensive, you can save money by using expensive braid solely on the top half of your spool.

​

As a bonus, you can keep the same backing on your reel for many years because you won't be fishing with it at all. A simple respool of the main line every year or two is all that's required.

Where do you get your braided line?

Depending on the size of your reel and the capacity of your line, you should use between 50 and 100 yards of monofilament backing. At least 100 yards of braid should be left on top of the backing, with the reel being filled to within 1/8 of an inch of the spool rim.
 

Braided line tape backing
 

As long as you don't use this method too often, the only downside is that the electrical tape's adhesive can degrade with time (though it normally takes years), causing the tape to loosen its hold and begin rotating with the line on the spool. The old tape must be replaced with a fresh one when this happens.
 

To get your spinning reel braid ready, just wrap electrical tape around the arbour of the spool. Because of its sticky surface and the tape's outer surface, electrical tape stays firmly attached to the spool, preventing any line slippage. Using this method, you don't need a backing to tie your braided line to the spool.
 

What is a braid-ready spinning reel, and how does it differ from other reels?
 

The spool of a braid-ready spinning reel is designed to keep the line from slipping. In most cases, the arbour of the spool has horizontal grooves that reduce the smoothness of the surface and increase friction with the braided line.
 

Additionally, some reels have rubber bands on the spool arbour that help to keep the line in place, as well as grooves on the surface. Most Penn reels, for example, come equipped with a rubber band similar to this one (see photo of Penn Battle II below).
 

It's crucial to remember that, although though most spinning reels come with a braid-ready spool, line slippage can still occur (particularly when battling large fish). When fishing with braided line, many fishermen still prefer to use a backing.

 

Advantages of braiding over monofilament
 

• Braid is great for finesse fishing with a light spinning rod setup because it has very little stretch, allowing you to feel what's going on with your lure or bait in the water. When you're fishing from more than 15 feet away, a lack of flexibility makes it easier to set the hook.
   

• Braid is less prone to twisting than mono because it doesn't have any memory.
   

• Even on a small spinning reel, braid's smaller diameter makes it possible to spool stronger line when needed.
   

• Unlike monofilament, braiding can survive for years without needing to be replaced (unlike mono, which degrades when exposed to the UV rays of sunlight, and needs to be changed more often).
  
  
  Mono is superior to baid in many ways.
   

• If you're just getting started fishing and aren't sure if you want to make it a hobby, you might want to go for monofilament because it's less expensive.
   

• Using a spinning reel with mono does not necessitate the use of a backing. To make spooling easier, you can tie it to the spool directly.
   

• The use of a leader is not necessary in the game of Mono. Monofilament can be tied straight to your lure or rig, however braided main lines should be used with a fluorocarbon leader to prevent scaring the fish.
