Ok, I just need to see if I'm understanding Copper well enough after reading a ton on it. It sounds to me like I need a copper set up for every depth range possible. Is there one standard Copper set up for spring such as 100ft and one for fall 400ft. If I"m running it off a dipsy I have a little more versatility. If the fish are down @ 70fow can I just fish 300 with a 400 set up. Or am I over thinking this. Just trying to stay economical. Heading up out of Oak on the 9th for one last killing time trip. Any suggestions?
