I too am not a crankbait expert but from the time we spent on St Clair last week I would say you need to play around with different baits and different retrieves until the fish clue you in to how deep in the water column, what crankbait, and how they want the retrieve. There is no magic crankbait, different conditions I would think calls for a different crankbait presentation on any given day out there. I will tell you this though always make very longggg casts, you want that crank in the target depth for as much of the retrieve as possible (I would almost spool my chronarchs on every cast). This is something I am determined to figure out on that lake and I cant wait to get out there again in a couple weeks to expand on what I learned last week. Good Luck out there!
This makes sense Tim, I'm not sure if I have the patience to figure it out. lol
