Looks like you go through the nose a lot. I would say that when you do that, you should change any one thing - speed, ball, revs, or axis rotation - and you'll get something more manageable. Oh yeah, I forgot the most obvious - move right 2 boards.
Leaving 4-7 or 6-10 makes it so much easier to mark.
I only get big-four etc when I try to adjust after a brooklyn and don't adjust enough. Funny thing about oiled lanes. You don't know where the oil is and sometimes adjust right into a puddle or a dry spot. When that happens, you just have to try various spots, not stay in the same place.
I see you have two very strong balls and a spare ball. It might help to get a weaker ball. I love the Jigsaw Trap, but it's got a mean hook. A weak ball - just something a little less hooky - will get you a different look on those difficult nights. Maybe a Tropical Heat or Nomad Pearl. I prefer more pearl than less, but a lot of folks here like the hybrids. I don't like solids except on wet lanes, where they really shine.
8-10 (which I call a Stoner in honor of Rob Stone) is just plain bad luck.
"If it ain't workin', you're either throwing the ball wrong or throwing the wrong ball."
"Follow the oil!"
"Dry lanes ain't worth a shot!"
"I love the smell of lane conditioner in the morning!"
