JQ,
Its difficult to assess your game without seeing you, but I do have some comments for your consideration.
Scout Reactive is weak ball compared to most equipment these days, so don't expect it to hook a ton. It is a excellent choice for the beginning hook bowler, so I'm not recommending a change yet. Work on a consistent release, learn to read the oil better, and work on adjustments.
Leaving the 2 pin definately means you are coming in too light. The 5 & the 8 are also indicators of a light hit. The 10 can also be left when you come in light and get too much behind the 10 pin.
Watch the 9 pin when you bowl. If your ball hits it on the far left side on a good shot, then adjust your feet left a 1/2 board. If your ball hits it on the far right, then adjust your feet right 1/2 a board. If you didn't get the 2 pin, then move your feet right 1 full board. (These are simplified adjustments, but they should work okay for your current skill level.)
As far as carrydown, it depends on the type and amount of oil, lane surface, balls used, etc. The key thing for a beginner is to watch your breakpoint. If the ball hooks later on a good shot, then adjust your target. On the typical house shot, you should find success by moving your target to the right, so instead of aiming for the 8th board, trying aiming for the 5th board. The outside of the lane is dryer, so you'll hook around the carrydown. If that doesn't work, then you can move inside, but you'll probably need to throw it slower to give your mild ball a chance to hook for you in the thicker oil.
So in summary, watch your target, breakpoint, pocket, 9 pin.

Good luck & good bowling
