Sunline High Weight Bass Fishing PE Line D-Braid was designed specifically for use on spinning reels.

With the increasing use of braided line on spinning reels Sunline wanted to develop a new line for maximum efficiency in bass fishing techniques that use spinning rods. It was designed with a core-sheath structure to provide stiffness to help prevent tangles and wind knots, while maintaining a suppleness for easy casting.

It is made from PE fibers that have a higher specific gravity than traditional PE lines. The specific gravity of D-Braid is 1.1-1.24 making it sink in water and helping you keep better contact with light lures.

When bass fishing with spinning tackle there are often times when your line is not tight with techniques like dropshot, shaky heads and other finesse techniques. With the higher specific gravity of D-Braid it keeps your line down more in the water, taking out the slack in your line and giving you a better feel of what your lure is doing, per the company.

It also features low stretch for high hooking ratio during the hook set, an advantage common to braided lines.

The fibers will also not absorb water, D-Braid features improved surface texture also to prevent fuzz and fraying from knot tying. D-Braid does not have any surface coatings that can wear off.

It's pink, which makes it easy to see above water, and since most will fish it with 5 or 10 feet of fluorocarbon leader, the color won't bother the fish.

It’s offered in 7, 9, 11, 13, 15, 19 lb tests, and in 131 yard (120 meter) spools.

It’s very pricey, at $40 a spool, but considering you can probably fish it a year without changing, probably a decent investment: Sunline America
