I've got a few of the PCB pins.  Just remember you're going to loose 1/2 of your
"free float" with a soldered PCB pin.  You just have to be careful when you
solder them to a board... careful that they are straight (rotationally).  The
mating connector with it's crimp on pins will provide a limited amount of
rotational alignment (ie float) so that the two meet flat.  I'd also leave space
on the PCB (assuming you use the 90° pins which allow the PP bodies to mount
parallel to the PCB) to mount the PP housings with a 4-40 screw thru the roll pin
hole.

Probably the easiest way to mount them is to assemble the PP's and mate with
another PP.  Then solder the PCB pins to the board while the connectors are
mated.  This is probably the best way (???) to assure proper alignment.
