There are members at Bass Resource who state that they target big bass. If you sit on the deep water abutting the spawning beds like some of us do or pounded Castaic Lake in its glory years like @WRBdid or chuck and wind big swimbaits like @Fried Lemons does, then you're targeting big bass and have a big bass portfolio like @Fried Lemons's, Tom's, @AlabamaSpothunter's, @Catt's, @Pat Brown's, Andy's, etc., then you do indeed target big bass.
I'm not part of the Big Bass Crew, but I do catch big bass for my nearly 45 degrees latitude. My approach is to catch a lot of bass and the big bass will come. I average about one four-pounder for every 30 bass. Remember that In-Fisherman said that a bass weighing X in the north is equivalent to a bass weighing 1.5X in the South. If In-Fisherman is right, my four-pounders are Everglades six-pounders and my six-pounders are Texas nine-pounders and my PB is a southern California DD. So, a northern four-pounder is a fine catch. Just ask Minnesotan @gim or Canadian @The Baron, who know how rare they are up north.
My approach is basically attrition. I dance with a lot of bass and sooner or later, I dance with a big gal. And some sweet mornings, I get to dance with five or six big gals, but along the way, I get to dance and dance and dance. I do know at least three spots that harbor big bass and when I'm casting at those three specific spots, I'm absolutely fishing for big bass, but otherwise, I'm just fishing and hoping and happy.
