I finally had my pool plumbing and plaster redone. I wanted to thank the group for the suggestions I was given. One very good design point was in bringing three return jets to the shallow end of the pool. The jets are pointed up and create a little wave motion to push the leaves into the skimmer in the deep end. My pool stays much cleaner because the leaves don't have time to sink to the bottom. For people with lots of trees around their pool I think this design element is an important one.
