RINGED ROLLER GUIDES and TIP-TOPS. Ringed Roller Guides are designed to allow large knots, leaders, and swivels--characteristic of big-game live-bait leader rigs--to easily pass through the guides when casting and retrieving. The special large diameter ring has been added to both the Regular Roller Guide and Regular Tip Tops, primarily for those who custom-build West Coast style Marlin casting rods, used for throwing live baits rigged to heavy leaders tied with large knots.
