welcome to the forums...
funny you should mention the "dent" thing...size of a basketball....I just pulled one out. popped right out easily, although, there is some minor scarring visible. I just used a suction cup hook, 'cuz thats what I had laying around the house.
anyway, there are pics in my photo gallery, if you want to see the size, location, and results. just click on my name, and select "view chuck's photo gallery".
