So heavier jigs and heavy wieghts on worms?
it totally depends on conditions - sometimes you can get away with 1/8oz, sometimes you need a full ounce. For flipping, heavier is usually better especially if you have to punch thru thick mats(but it sounds like this place isn't very weedy). Deeper water will often call for heavier weights, as will windy conditions. Fluorocarbon and braided lines are more sensitive than mono, so you can effectively use lighter weights... there are lots of factors, and no real 'rules'.
For myself, I'm almost always fishing shallow water(usually 10 ft or less), so I keep 1/8, 1/4, and 1/2 ounce worm weights in my terminal tackle box. For jigs, I use both 1/2oz(for general use) and 1 ounce weights(specifically for flipping).
And like mentioned above, don't forget deep diving crankbaits for deep(er) summer bass, which can often stack up off-shore.
**I'm specifically addressing largemouth bass here, as my smallmouth experience is limited to wading clear rocky streams.
