simple way to remove LCD withoud cracking it

I have seen countless comments about the LCD breaking when trying to remove it from the LCD shield with adhesive. I have found a simple solution. Once the 4 screws have been removed take a piece of fishing line (longer than the iPad) and simply run it beneath the top of the LCD from one side to the other. Once it's in place, gently pull it down applying equal pressure from both sides. The fishing line will break the adhesive in the process, freeing the LCD. It has worked for me every time.
