Ok, this is kinda crazy for me, since the most mechanical thing I've every done is change the oil in my car...but,
I took the piston apart. (rings, head, bearings, etc.) and i showed them to my friend, who has actually seen a bad piston before. He looked at the head, rings, and cylinder and said all were perfectly fine. The cylinder itself is flawless. the piston head has no scratches, just some light rubbing near the bottom. nothing that changed the shape. and the rings are still in tact, spring'y' and looking good he said.
