Do you have the toothpick on the shelf or behind the strike plate? If it's behind the strike plate, remove it. That will help accommodate a heavier spine. Raising your brace height and a heavier point, as others have mentioned, should complete bring it into tune.
Can only do so much with brace height though. It won't correct 5 inches of shooting left because of too stiff an arrow. Brace height may move it an inch or less. removing the toothpick behind the side plate and heavier heads will show much more substantial results.
Try the 225s and see what happens. Won't hurt the hex heads by shooting them into a bag, but will tear down the bag more quickly than field points.
