I'm rigging up for the trip to the pier Saturday for some spanish fishing. Got bubble rigs ready, and am working on Gotcha and Looney rigs now. I am planning on using two different types leaders for the Looneys and Gotchas, 40 lb mono and 20 lb seven strand. I am eliminating swivels as suggested and tying leaders directly to 12 lb mono mainline. Plan on making leaders 18" also as suggested. I can usually get max casting distance on lures like this when I let the lure hang 8-12 " from rod tip when tied directly to the lure. My question is with a 18" leader do I need to leave the knot out beyond the rod tip when casting or can I reel it up into the tip? If I reel it into the tip will it affect casting distance? More importantly will the knot damage the rod tip?
