I have both the old and new.

I just weighed the new column and base at 160 for the column and 180 for the base. The new column does look to be a bit lighter. The new base looks to be a bit heavier.

It will be a few weeks before I pull the old one down so I cant give weights right now.. I expect about 20 pounds or so lighter on the column and for the new base to be 10 or so heavier.
