Mark's book is a good one to have, but for inlines IMHO there is no correct dive chart as inlines are completely depth/speed/line size dependant along with trolling with/across/against the many currents out on Erie. It is very easy to find out the actual running depths for the day and once you get a feel for them, you have a pretty good idea on the lineouts to start with every day and go from there. Running harnesses, you get more lift out of a #7 or #8 blade than a #3 or #4 blade, Just don't put to much into thinking about it. Running 4 inlines and 2 bouncers, the bouncers go near bottom, run your 1oz inlines 25, 35, 50 and 65 back and let the fish tell you where they want it. Alot of the times the big girls hit a 1 oz inline at 10 back even in 50+ feet of water. You don't get as many bites but typically they are good ones. Those numbers ( unless your fishing 24ft and less I have starting numbers for that too) are a good starting point. Then you don't have to remember anything else. Just my experience.
