The best way is to not rebuild them and the reason is that there is no reason to rebuild them.

The actual question is: Why do you want to rebuild them?

"Believe"? What belief has to do with tuning? Tuning is a matter of science not belief.

Regarding Index Rebuild s. the presentation of Richard Foote http://richardfoote.files.wordpress.com/2007/12/index-internals-rebuilding-the-truth-ii.pdf

Table Rebuild can help only for FTS's, because it sets the HWM lower.
