When PowerPro engineers began developing a new PowerPro hollow-core line, their goal was simple: Create the next generation of performance hollow-core line with superior structure, durability and connection strength. The outcome is Hollow-Ace. With Hollow-Ace, anglers can make a highly-efficient knotless splice that achieves strength translation near 100% compared to 65% to 70% with a typical knot. Additionally, Hollow-Ace is much easier to thread than other hollow-core products. Fish with confidence, fish with PowerPro. Features: 16 spectra fiber construction creates superior connection strength Enhanced Body Technology delivers incredible abrasion resistance and strength to diameter ratio Bulk spool log sticker to monitor the amount of line used for each application 3000yds comes in standard bulk spool dimension (compatible with standard spooling machines)
