Anyone else do a Cube? I have been getting really far with mine and have learned some strategy, but there are still a few things I'm lacking. I'm looking for a little bit of help.

I know one strategy is to finish the corners and then work with the inside cubes, and I have gotten to the point where all the corners were done (twice), but couldn't manage the inside (which I heard was easy at that point). How to do this?

Is working from top down really another okay strategy? I assume no, but someone was mentioning it (they havn't solved the cube yet though).

Any other tips would be helpful. I want to go it and become good at it.
