I was looking back on some pics of people using the hammered jigs and catching everything! I am new to jigging and have a few questions about it that particular jig. 1. Is it best to tie the jig directly to the mono leader or is it bestto use swivel and split ring? 2. Most come with a hook attached. If their is no split ring connecting the hook, how do you get the old hook off? Thank you! More than likely more questions to come!
