I have broken down long, shark-like patterns in 10 minutes with 6 on a pair. As you guys have said, you gotta have the time and you gotta be careful. If you are trying to create friction and you pull couple, you remove any chance of hold inside. Likewise, if you are trying to carry oil down and push it, you will create an even greater hang spot.
The thing that is just as important as breaking the lanes down in your favor is watching what the other bowlers are doing. Stay inside the guys throwing charcoal. Stay outside the spinners throwing shiny. If you switch lanes between games, try to keep an eye on what they are doing there as well.
