>>From my understanding pyramiding will never go away but hopefully over time and with proper care it will grow into the pyramiding which should be less obvious...I guess it all depends on how bad the pyramiding is.

In my experience this is true.
Our tort was 9.1 lbs when we took her in July of 2002. She was horribly pyramided, now 5 years later she still is but as she has grown the appeance of the pyramids has lessened.
She'll never be "normal" but proper care, free range grazing has helped a lot.
