Jim,

I won't claim to give any final answers.  The debate goes on.

Here are my thoughts:

1.  In the flying picture, your nose is a bit high but not dramatically so.
Do you know if your yoke was at the maximum elevator up stop when the
picture was snapped?  I'm guessing not but I really can't judge from the
picture.

1a.  I note that the bottom of the nose wheel is about 3 +- inches higher
than the bottom of the mains.

1b.  If this plane touched down in this position, I think the nose wheel
would touch (and swivel) before the weight came fully onto the mains, due to
the shock absorber travel.

2.  If the snubber cable were removed, the nose gear would always or almost
always touch before the mains were carrying a lot of weight.

2a.  Still, the nose gear swivels to line up with the direction of travel,
thereby providing little side load.  The mains do not swivel to line up with
the direction of travel and DO provide substantial side load - that's what
turns the plane to line up with the direction of travel.

2b.  Coupes with no snubber cable land all the time with no side-load damage
or loss of control.

3.  If the snubber cable were removed, there would be much more shock
absorption for the nose gear.  Nose gear damage and subsequent damage to the
engine mount happens and is expensive.

4a.  With the snubber cable, a drop in landing has more potential for damage
due to reduced shock absorber travel.

4b.  Unproven: with no snubber cable, there are control issues in strong
crosswind landings.

Proposed test:

Would you guys with no snubber cable do some strong crosswind
landing-in-the-crab testing and tell us your results?

Would you guys with snubber cables consider doing that testing both with and
without them and tell us your results?
