Tri-level sync question

A question for anyone who has done dramatic work with Panavision 600 and
tri-level sync either with Ambient Lockits ACL 202 CT or DeneckeSB-T:

I have heard that there are major post production problems if sync is
interrupted (intermittent BNC cable or connector) and that most everyone is
perfectly happy (re-recordists editors et al) with just cross-referenced TC
even on two-camera jobs. Without video sync it might mean that TC would be
out at most, one frame between the two cameras. Is it worth the risk of a
fatal flaw, (green mask frames and sync gaps, VERY BAD!) with tri-level sync
to use it instead of simple cross-ref TC?

Inquirering minds want to know.

yea it is a little more work
and the offset chages a few frames everytime the cameras are turned on
and off --- so what
but why not do TC slates as usual and let post do the worrying?? and
spend the extra time of a poorly paid assistant ( probably on his/her
first job on a flat)
why this elegant high tech expensive ( $50 a day per camera) solution to
a time consuming post problem - the solution is either the Dennecke or
Ambient sync boxes that as you say correctly have to have 2 good wires
going to camera and fresh batts every 24 hours.....
of course then there are prouductions that require decent sound righ
away as they start cutting right away...

you got to go with double system though.... some of the F900 have
intermittant sound probs ( small half second drop outs)

and then there is my book - you all know about that.......
