What makes it different from other Firelines is the use 8 carrier or strands of Dyneema that are fused together to produce a braid that is 4 times more abrasion resistant than the original Fireline. 

The 8 carrier construction offers several key benefits to Fishermen. Ultra 8 casts 10% further than traditional Fireline. Enhanced knot strength and near zero stretch deliver unsurpassed feel. Round fused profile resists separation or digging into the spool under heavy loads. Construction optimises Ultra 8 for light to medium duty spinning reels. 

Berkley Fireline has long been renowned for resisting wind knots far better than un-fused braids, and Ultra 8 takes this to a whole new level.
