When you have difficalties with the Lane conditions,First,try to get a good feeling about your Balance and than work on your ball speed.Howfar are you standing from the faultline,How do you hold your ball.Measur your steps.For curve ball,the position of the hand,the release of the ball is important.
When you have a poor condition,you can try to give the ball more speed,by standing farther away from the faultline,hold your ball not to low so you can give the ball a great swing.And for a rich condition try the opposite..
When you have the permission to walk alongside the Lane maybe you can see till how far the Lane is oiled,this is also the position wher the curve ball get his grip and goes from slide to roll and hooks.
Maybe you can do someting with it,keep on practice
