I would assume your a lefty *?*  Normally when you hit flat seven or ten You need to tighten up your line and hit the pocket a little higher.  How you make your adjustments to get there is up to you.  The thing to remember about the red, white and blue oil patterns is the oil is flatter on the lane.  Meaning, your not getting that funnel shot you'll normally see from a THS.  Accuracy is also key when bowling on flatter oil patterns.  Good Luck and Good Bowling!
