well it wasn't too bad

I used a curved upholstery needle which really helped go through the webbing, I also used Spectra line which is very slick and went through pretty easy (it's also damn strong stuff too!)
I doubled up the line and tied a double nut and then went to stitching, every once in awhile I'd leave a loop on the one side, pull the needle/thread through the loop forming a half hitch. When done I'd tie it off and then used a lighter to melt the line down, gave it a squeeze w/ my fingers- it acts much like paracord in the way it melts down. Won't win any sewing awards but appears to stout enough.
here's a pic of the annex clips I'm using on the empty side- shows clips open and slid on the pals webbing (you can also see a wood blade I have slid in the pals webbing on the rear of the holder and a 25' yank of 2 mm Spectra on the same side as the annex clips)
annex clips closed w/ new webbing for compression straps
