I dont do much lake fishing, but we have smallmouth and largemouth in most of the rivers around here...You usually find the smallies and green bass in different locations in the Summer time. You might catch several of each out of a decent riffle pool complex...but the smallies are usually in current at the heads & tails of a pool. The greenies seem to like slower water. The same lures work for both.

I don't catch many largemouths on tube baits around here, but the smallies love them.  

 

Wow, largemouths kill tubes here in NC....
