In my job (Train Signaling) we are very conciencious about crimp
connections. All specifications demand that you use the tools made by the
manufacture specifically for crimping their connectors. The only thing that
is seldom mentioned but equally important is the stripping of insulation
prior to installing the connector. It is important to use the correct wire
stripper size.
I've even gone so far as to crimp & then solder in some installations
(primarily high use test connectors).

I've had failures with these too. I replaced a Centipede harness that had
the split pins.
In my opinion the split pins are more "fragile" and do not seem to hold up
to abuse as well. Example being in the particular Centipede the op had been
swapping boards on his own for awhile now & finally realized that the
problem was more than he could handle. (Of course he had probably made it
worse swapping boards, but there was no visible damage).

shrinking to solder tail edge connectors? Heaven forbid you break a pin and
have to start over.. At least with the crimp style, you can replace a single
bad pin if need be.

Yes I like this feature too & I like it when I need to add to a harness.
