that's a nice report and some good fish on the fly rod. i fished the c/a tournament this weekend and there were plenty of fish in the 40 ft range suspended at 25 feet which is tough to get to with a fly rod even with 350 grain sinking line like i typically fish. i just ordered some 450 for my 10 wt for days like you described above when you need to get down quick with the current and tide running in the same direction you don't stand a chance at fish below 20 feet with anything less than 400 grains.
nice report and nice to hear someone else valuing their time on the water with a youngster. i've got an 11 month old at home and the wife gives me the green light every now and then and i take it without ever asking are you sure. enjoy the time when your little guy is stationary - mobile is a whole new lifestyle.
