Where I come from, Colorado, Lake Trout hit very, very, very light. Always, no matter what the method or bait that you use. I can school the Lake Trout on my jigging rod, but thats it, I rarely get one on a tipup, or rarely even get a flag. But a lot of times my bait is gone, and the tipup is even set to where a slight twitch will set it off. Any tips on getting them to set it off, or any locational tips would also help, as I get very few flags. Lakers are always near the bottom here if that helps, as we have no suspending minnows.
