Depends how much of a struggle you want to accept in putting on a
lightweight filler, or struggle in sanding-off a heavy weight filler.

The other problem with lightweight filler (ie the stuff made with Expancel)
is that it marks very easily (and permanently)  in service. I wouldn't do
mine so light again.

A tip for mixing hte lightweight option is to pound it vigorously for
several minutes. There comes a point when the mix goes from appearing too
dry to a plastic putty-like consistency, which is much easier to spread. The
addition of fume silica helps this greatly. Let me know if you're interested
in the ratios I used (which might answer your original question!).
