Best pole? Depends on how much you want it to weigh. Fiberglass poles work just fine but you can get custom to fit carbon fiber poles from Fibraplex if you are counting grams/ounces.
And in case you use a CRL (continuous ridgeline) and need to stop the pole from going fore/aft you can attach a prussik onto the CRL and affix it to the pole stopping the pole from moving one way or the other; this negates any sewing into the tarp ridgeline.
Not long ago I received a cuben tarp from one of our well known vendos with pole pockets and a tie off for the pole--after setting up the tarp I discovered the tie off was no where near the center! Must have been a bad day to make the tarp-the prussik was a quick simple effective fix.
