I should have been more specific. What I had meant above was that the saddle fore/aft position relative to the saddle rail clamp of the seat post should be set for balance, whereas the seat post offset should be used to adjust reach.

For example, if the saddle rails are clamped toward the rear of their useable range, then a rider sitting on the middle of the saddle would tend fall forward and put too much weight on his/her hands (as you had described). It may be better to get a zero offset seat post and clamp the saddle rails at (or slightly forward of) the middle of their useable range to adjust the balance while maintaining the saddle fore/aft position relative to the bike frame.
