I did my old board with the Lava solderless kit. Huge pain in the ass. Every connection has about four ways to fail. Strip too much? You'll probably short the ground. Strip too little? The center won't make contact. So how much is just right? You have to figure that out yourself, based on trial and error.  And there's a very narrow range that's correct. Didn't manage to keep pressure on the cable as you bent it to attach the right angle cap? It probably pulled out of the sleeve. Tested the assembled cable and it was fine, but once you installed it in your board, there's no signal? Pull it and start over. Something was Juuuuust barely working when you tested and now you've wiggled it out of sort.
Did my new board with the cheaper, and less well regarded D'addario solderless  kit. You clip the cable, undo a screw, slide the Jack over the cable, and tighten the screw. One of the ten jacks in the kit seemed to have a problem (wouldn't connect to the ground shield) but compared to the trouble I had with the Lava, I'm completely sold.
