Changing line

[zx150]

I had a guy at Bass Pro tell me that braid is nylon line and it really does not go bad.

Reel magic coats the line. It makes it more pliable to me and easier to cast. Not sure if it is actually asorbed.

It's monofilament that's made from nylon, which does absorb some water, and is subject to breakdown from exposure to light and heat, which is why you need to respool mono periodically, even if you haven't used it. Braid, on the other hand, is made from different manmade materials, like Spectra or microdeema, and is virtually impervious to the elements, so it doesn't just "break down" over time, like nylon does. But it does get frayed and nicked with use, so you need to trim off the used portion periodically. As long as you're careful not to use frayed or nicked line, it will last for years, and I don't see the need to reverse it. But maybe if you do use it that long it loses castability or something, I don't know. Fluoro also doesn't absorb water, and is very resistant to uv light, so it doesn't break down from exposure to the elements the way mono does.

Oh, and if you're using braid, please don't tie it directly to a jig. Use some kind of snap or leader or something that can bend or break away. Braid is nonbiodegradeable, and presents a serious hazard to wildlife if left in the water.
