Many years ago when I developed the idea of an impregnated synthetic piece of line on the leading edge of foils, keels, bows, etc., I did not consider using three lay line for this purpose. I always used braided Nylon or Dacron line with the thought that it would have greater non-directional strength and resist damage from blows better . I hope this line will be fine though if well impregnated and covered with sufficient sheathing.
