I always carry a box full of spoon type lures, but mostly give them water time when things get slow. Where I fish for koks, there are other lures that will out produce these. I have used the spoons with the flipper's, and the ones I had the most sucess with were the copper/red head , pearl/redhead & rainbow (kokanee special) needlefish.
Another one that I've had success with is the "kokanee King" series spoons with the flipper tail...same colors as the needlefish mentioned above. I usually ran dodgers with around a 24" leader. It doesn't take much to destroy the lures action with corn, so usually we'd just use gel scent.
As far as Apex's with the red flipper, I think they are more for trout. I remove the flippers and re-rig them for koks.
The needle fish and kokanee king spoons are great choices to put on a leader with a duo-lock snap on the end and attach on your line when you allready have your presentation down at depth. It will slide down your line and stop mid way on the bow.
