For largemouth in the fall, I always start on the bank targeting the inside grass line...at least until the water gets down into the 40's.
If it's overcast and calm, topwater gets the nod. I will catch fish on frogs in water most people think to be "too cold" for that. If there's a breeze I will hit toss a swim jig, or shallow running crankbait, and if it's really windy, a bladed jig.
When the sun pops out,and with all the boat docks pulled, I focus on grass. The "edges" in the grass than docks made get targeted with wacky rigged stick baits, soft jerkbaits, t-rigged craws/creatures or jigs. If they have slid back out deeper into the grass, I use the same with a little more weight. If they are out side the grass on the deep edge or on rock,a football jig, swinging jig head, drop shot, or shaky head gets the call depending on how they are biting that day.
For smallmouth I like football jigs, tubes, wobble head jigs, and dropshotting. they never seem to come shallower than the deep grass line in the fall. I break out the blade baits when the water gets into the low 50's.........or I should say, I start using them when the calender flips to "fall" but I don't seem to catch much on them until the water gets colder, but I give them a good try in usual smallmouth producing areas almost every trip from late Sept. on just to see if that bite is "on" yet.
Deep cranking for either can be really hit or miss in the fall for me. The fall jerkbait bite can be quite good, but is grass and water clarity dependent. In some years the grass stays too thick, or the water stays too murky for it to be a consideration. Same goes with lipless cranks. Often times ripping them out of grass like I would do in the spring is an exercise in frustration in the fall, as the grass has become fragile, and instead of getting clean "rips" out of it, it just pulls the grass...roots and all right back in a huge wad to the boat. Now, if I get grass/water conditions in the fall that allow for both, I use both.
