Method 1 is best, i.e. only two leads (one from each side) hitting the wave at the same time. Think of the IC as a rake. If all the leads on one side of the IC hit the wave at the same time, the IC is effectively acting like a rake. Solder will more likely be retained between the leads thus creating bridges.
