The floater... learn it
I haven't learned this just from watching Parker, Rose, Wade, Jamison and other players who use it efficiently... but it's just the perfect shot. It takes shot blockers out of the equation, it conserves the body from the pounding you take by driving all the way, nobody knows when exactly you will flip it up keeping them off balance, and it conserves energy. Since I have developed a consistent floater, my game has been expanded to new levels. Also, it's fun to practice. I like just messing around and throwing up floaters from like 15 feet out just to help with my touch... and floaters definitely do help with your touch. If you haven't learned how to be effective with this shot yet, I highly recommend putting in some time and learning it.
