The third is a too long setup for my taste. I like to come closer to the tip. Like Altissimus said, the biner on the Ds is unnecessary and adds an unneeded length.
Also, I'm not fond of the first. Safe but not practical. The issue is the biner on the splice used as the main connector on the saddle. When you need to move your setup, you can only unclip the biner with the pinto. No problem at first seeing, excepted you have to deal with the rope's tail getting in the way.
It's better to clip the pinto's biner to the Ds as the "stay in place"and then the splice's biner is cliped on it as the "flying end" of your lanyard. Actually like your third, but clipped on the pinto's biner instead of chocked.
Last point, I'd put the pinto with the tail coming out on the underside. I find it easier to take the slack out, more ergonomic, and with less parasitic friction to give slack. But that's just me.
