Over the years I have changed the way I fish and this includes the change from using strictly monofilament lines to the more sensitive and stretch free braided lines. I still use mono in my set up, it is just for a different reason now. Regardless of the type of braid you prefer to use I would recommend you include some of the monofilament as a backing and here is why.
Most braided lines are far more expensive than the cost of most everyday monofilament lines so to reduce the cost for getting on the water and to make that braided line go farther I suggest you fill half of your spool with a monofilament to work as backing. This will fill a large volume of the spool and leave you space to attach your braided line to it using the knot of your choice. Be careful that you choose the proper knot for attaching the two simply because most braided lines are a little slicker than mono. I use an alright knot but others work as well. Basically half and half is the ratio I use but you can always go heavier on the mono if you choose. The major benefit from this is that you will never be able to cast as much line out as your reel will hold. By tying the two together you reap the benefits of the braided lines strength and sensitivity for your hook sets and you don’t have to spend a small fortune.
