They work! Almost too good at times - if they are very aggressive and schooled up during warm water months - you will have a lot of swallowed hooks if you are using the tiny jigs. I fish a deep, clear water, upground reservoir where they school up near the pump houses and they compete to get to the bait first some days. Up size to a ball head 1/32 with a kip tail dressing to slow the fall - helps with not as many gut hooked and weeds out a few of the smaller fish.
