Having not fished there I can't tell you the hot bait, but no doubt Jenna is right. As far as quickies, you can fish them many ways. Sometimes the bigger ones can be flatlined and do extremely well. I have done that quite well on long flat backtrolls from 6 to about 15 feet. Flatlining a K15 will get down maybe 6 to 8 feet or so. But a downside to that is it requires a lot of line out. So usually drifting we use divers from the smallest to the Jumbo Jets. Depends on water quality and flow over a hole. Smaller quickies don't dive as deep either. Fish can only look up but they have to be able to see it.You want to work the hole slowly so using a diver allows you to get the quickie (or egg/shrimp cocktail) down fast and with less line. You get to work more of the hole, especially the top of the hole. A smaller diver will get it down in most drift boat runs.
Do not use flashers back trolling in a small river or anywhere they will bump the bottom. When they tangle, and they will, you will spend time trying to figure or what is not right before reeling up a cluster of immense proportions. Which will require re rigging and being one of the guys who spends most of the day not enjoying nature let alone fishing. Keep the presentations simple.
Sardine, tuna, herring any might be better on a particular day. Start with sardine. Really good fishermen will bring two. Guides might have four different types of bait.
Least that's what I've seen.
Hope that helps.
