I don't feel like the 550 cord gets in the way, but the chances of it doing so aren't zero. Total distance of the cord between the sticks is less than 23", with a little leftover at the front in case I want or need to lengthen it.
I attach to the front through the hole that would be used for mounting the deployment lever for left handers with a pretty simple knot.

The back is secured with another self tightening knot around the pole. Use whatever you see fit. I don't even know the name of this one. Maybe two half hitches? I might change this out for a round turn and two half hitches.

The back rest sits just behind the sling swivel stud.

The front is adjusted to ride where I like it to accompany my hand position by lengthening (or shortening) the 550 cord.
