I have read over TalkCricket's description of cricket. And from what I can interpret from your question, you are spending most of your time in recovery. You want to know what the best line for the pickup of a new pitch, and you have pain in your back that prevents you from throwing the ball quickly, and you have no hand to use for low recovery.
From this description, it is very hard to tell what is being asked. Since we cannot read your mind and do now know what you are asking, it is difficult to answer the question.
I suggest you visit some of the cricket strategy websites, such as PitchVision, MyCricketGame, and Dangermouse. Once you have figured out what you are looking for, Google is your friend. Sports Stack Exchange can also help you, but the members need to know what is being asked first. Look at the links provided and try to determine what the question is, and then edit your question to make it more specific.
