Jon,
My buddy Bill is in for Sunday. He wants to launch at the Haddam Meadows ramp, which is cool because there's a spot I want to try there as well. Maybe we'll make a run down to the canal and try it again. High tide in Haddam on Sunday is 9:30ish, which means we'll be fishing the last two hours of incoming, the slack and the first two hours of outgoing, as you suggested.
