[Elecraft] Anderson Powerpoll connector

I have to admit that I am not a fan of APP's either.
I just cannot relate to the voltage drop across the connectors when drawing 20+A.
On my rig (with its factory built cable) it approaches 1.2 Volt. (And yes, the connectors do get warm!)
Even with decent cables that I have made using 4mm wire and 45Amp PP connectors I still see .6 to .8V drop.
That to my mind is not acceptable.
So, once the warranty expires on my K3 (in May) I am going to ditch the APP's and solder a fly lead of 4mm twin lead wire directly to where the APP's were or look at some (better) alternatives.

  At the risk of re-energizing an old debate, I have *never* crimped a
  PowerPole connector and have *never* had a problem. All of mine are soldered
  just as Elecraft recommends if you don't have the correct crimp tool. 

  In the APP Power Supply Cable Kit instruction sheet is a detailed cut-away
  drawing of how the APP connector contacts insert into the shell and lock for
  solid, reliable contact.

  I guess my problem is: after reaching a certain age I have developed a bag
  full of skills, which have served me very well for over a half century.
  Installing small connectors is a piece of cake, that is until I came against
  the APP.  Didn't think needed to read the instruction sheet.  After all, I
  should be able to correctly install this with my bag of knowledge, right?
  Now that I have achieved a higher level of connector expertise, I still
  prefer the Molex, but that's me. 
  Also, something about having to buy a $30 crimper to do the right job tends
  to rub me in the wrong direction as well.
  Thanks for the bandwidth.

  lip on the connecting pin (the part that's soldered onto the wire) extends
  completely into the plastic housing so that it locks itself over the metal
  part inside the plastic housing.  Viewed from the side it looks something
  like this:

  soldered onto the wire, the diagonal slashes represent the lip at the end of
  that connector, and the single line of dashes represents the metal part of
  the plastic housing.  If you can pull the wire out, it ain't locked in
  place.
