Landlocks are short strikers most of the time, unless you hit them when they're actively feeding. They went off the metal bite for us well over a month ago. Just keep fishing, there's still plenty of silver fish willing to bite. Or, should I say, nip :-( Captain Bobby!!!
this time of year i fish a little more aggressively, pick the boat speed up a little, drag is set tighter, and up one size on the leader. copper and stainless long line is working better for me over the down riggers right now which adds stiffer rods as well. i fish sebago and that may play differently
