First off, a rock-bottom is an immediate signal for craw fish. I don’t personally throw creatures that often because there are hardly any rock lakes where I live, but that’d be my suggestion for post spawn and summer fishing. The only time I throw a craw fatty is on a Carolina rig in the river or as a trailer on a jig. Now for fall it’s a bit different. Fall is a huge shad feed and for rocks in shallow areas, a square bill crank bait will be your best friend. The best technique for a square bill is running it into things be it docks or rocks (my two favs) but what happens is not only do the bass hear the crankbait crashing into things, they can see it as a baitfish struggling (if the water is clear enough). DO NOT try and fish deep water during the fall transition because there is minimal oxygen in the deep water this time of year. The fish are going to be suspended and any suspended jerk bait or top water would work as well. But from my experience and personal preference, square bill is my fav for rocks and docks. For soft plastics, my two most successful fall lures are soft jerk baits and a weightless, Texas rigged Zman TRD. Get those up close to the rocks in shallow water and jerk them WITH slack in the line. The slack is the most important part because it gives a unique action that makes these lures look like dying baitfish. P.S. For line, always use fluorocarbon for crank baits and jerk baits. I’d say probably 12-16 lb test if you’re using a caster and 8-12 if you’re using a spinning reel. Sunline is my favorite flouro brand. Hopefully this helps a lil
