I always like the Pomme arm any time of year over the Lindley because there are more areas that I like to fish. Just a personal preference. If you fish the Lindley arm in Oct/Nov always hit Haverstick branch - it is a stump filled cove and shad pack in there so tight you can walk across them.
As far as stump fields; I already mentioned Haverstick on the Lindley arm. The Pomme arm: Coopers Cove, Fugat/Big Hollow, Twin Coves, Possum Creek, all are heavy stump fields with standing timber and laydowns/brush piles in water 1-25' deep. If you don't already having a fishing Hot Spots map for Pomme, pick one up. All the areas I mention here are on there.
FYI the lake is 5' low and will be that way for a while. The better bite is along bluffs right now because of the water level change. Spinnerbaits, buzzbaits, square bills, parallel to the bank on the bluffs in 1-3' of water. You have to nose your boat right up to the bank and cast parallel.
