The news I picked up at the sportsman show from a couple of lodge owners is that they are expecting another banner year. Apparently last years fish were 3-4 year olds and this years stock will be 4-5 year olds. I don't know how they know this but I'll let you know July 23 when I get back.
I did very well last year with sardines on a 6' leader behind a flasher trolled very fast.
Look for the Canadian boats and match there speed, if you don't get out of there way!
That was advice I received hope it helps.
