For reference: <BR> <BR>2001 Malibu 23LSV 22mph <BR>600lbs in rear + 4 people <BR>600lbs in front (ski locker and walkthrough) + 2 people <BR> <BR>With wedge down will I get more vert or more ramp? How does it effect the width? How much difference in size should I expect?

You will get more vert. I find that wake quite dull without the wedge. The difference will be quite noticeable. Watch it though, the Wedge can break.
