When our engineers began developing a new PowerPro hollow core line our goal was simple, create the next generation performance hollow core line with superior structure, durability and connection strength...enter Hollow Ace. With Hollow Ace you can achieve strength translation near 100% compared to 65% - 70% with a typical knot. Much easier to thread than other hollow products. Utilizes a 16 spectra fiber construction to create superior connection strengthEnhanced Body Technology process creates incredible abrasion resistance and strength to diameter ratioBulk spool log sticker to monitor the amount of line used for each application6 sizes = 40, 60, 80, 100, 130 & 200 lb.3 colors = White/Hi-Vis Yellow/Marine Blue4 spools = 100 yd for making your own Wind-On leader, 500 yd Box and 1500/3000 yd Bulk spools.
