I notice from Youtube videos that most east coast people tie heavier leader to lighter mainline. I can totally see the benefit of doing that. I can see using smaller reels fill with 500 yd of 50lb or 65lb braid and 80lb or 100 lb of fluoro leader to fight big fish with 20lb -30lb of drag. In California, most people use or tackle shops recommend lighter leader with heavier braid. People here use bigger reels filled with 65lb or 80lb braid but only fish with 30lb or 40lb leader. Is it just a marketing strategy that the tackle shops here use to sell you more expensive reels or lines? What am I missing here?
