The #10 and #15 whipping twines from Robline are more heavily waxed and braided and will not unravel because of the flat, strong seam. Use #10 or #15 in heavy-duty applications. Waxed Tackle Yarn Whipping Twine - White - 1.0mm x 46M- #10.
Used this for some seen eyes on some ropes, nice and strong and very good handling, especially considering to unbraided. Will buy again once I run out!
