Thanks for the replies- hope I did not make a mistake! A guy at Cabela's recommended the Nauticpath and one of our party used it last year and thought it was great-so hard to go against it without positives for Navionics. I also heard some concerning things about the Navionics for the east basin and thus, all things together, pulled the trigger on the Nauticpath. I also figured since shipping charts are the basis for it that it should be pretty accurate. We will see.
