Posted for N295VV@aol.com:

Well, there are shoulder harness and there are shoulder harness.  The one
supplied with my kit is a piece of junk.

I was in a crash  of a plane that had dual shoulder harnesses--better, but
not perfect--they had no cross-over buckle holding the two shoulder straps
together, and my son's shoulders moved back at impact, and he slipped out of
both harnesses and hit the instrument panel.

There was a magazine article a couple of years ago that charted impact speed
vs. surviveability.  Anything over 70 Kts was fatal.  So, if we land at 100
kts, as is suggested for a LIV,  anything less than a four-point racing
harness is less than desireable, and in Tony's case, a single cross strap
probably would have been useless, in my opinion.

A four-point racing harness, however may have saved him, depending on the
G-forces involved.
