Power Pro Hollow Ace is made from the same materials as the standard Power Pro Braid Fishing Line we have all enjoyed over the years. The Power Pro Hollow Ace is a hollow core braid that allows the creation of finger spices and the formation of loops for wind-on leaders. To be the best hollow core braid Power Pro knew it had to have an incredible abrasion resistance and strength to diameter ratio plus create a rock solid splice. They utilize a 16 spectra fiber construction to create superior connection strength plus Enhanced Body Technology creates the next generation of hollow core line. Power Pro Hollow Ace Braid has superior structure, durability and connection strength plus allows for easy finger splicing or loop creation.
