In this episode of Mastering Rod Building, we discussed the KR Concept Fishing Guides, the evolution of modern guides, and what sets them apart from the competition. We discussed the groundbreaking New Guide Concept (NGC), which proved that guide trains could be constructed from smaller, lighter guides that resulted in better rod performance, leading to the KR Concept. We discussed the importance of guide height, the need for guide redesign to maximize performance, and the differences between the Fuel KR Series of guides and the rest of the competition. We discussed the importance of using Fuji guides to get the optimal performance advantages of the KR Concept and the new availability of KR Guides in the Concept O Rings, which offers an attractive price point while still delivering all the advanced technology of the KR Concept. Finally, we provided a link to our website, which contains more information about the KR Concept for anyone interested in learning more.
