I think a rattletrap is the best fall bait. The crankbait is good, but only good if you know there exact depth. A rattletrap will cover every bit of the water column until you find them. But I'm guessing you have grass on your lakes. target that grass with the rattletrap because fish will always move on them to feed. The grass puts of oxygen, there are baitfish present...so it's the perfect spot for bass to sit and just gourge themselves. If it is 4' and shallower, burn the rattetrap, if it is deeper slow down a bit. Also, to make the rattletrap more weedless remove the back hook and put a #1 or #2 treble on the front. You will have more solid hookups, it will be alot more weedless, and the large hook will play a 10lb+ easily. My favorite rattletrap is the Spro Aruku Shad in perch. I also like the Yo-Zuri Rattl-n-vibe in shad and firetiger colors.
If you find deeper fish feeding on baitfish, then the crankbait can be good. Have a wide variety. My choice would be Rapala DTs. Have a couple DT-10's and DT-16's in bluegill, silver, and firetiger. When you get the bait down to it's max depth stop reeling. Let it sit for about 3 seconds. Then crank as fast as you can for about 3 seconds. Then let it sit for 3 seconds and repeat that. The violent stop and go will trigger reaction strikes out of feeding and non-feeding fish.
Hope this helps.
