Ya, I'm not pulling a semi out of a ditch. We are talking a 2000lb sxs, with a 4500lb winch. At most, I may have 3100lbs when attached to my skid house pulling at an angle. The galvanized pipe used as dock legs is more than adequate and readily available as scrap in my region, as folks move away from steel docks/lifts to aluminum.
If I have something solid laying around, I may consider it, but I still have to cut it to length and drill a screw hole to keep the strap centered on it. I will be sure to test it before having to rely on it for sure. But I'm guessing it will be more than adequate being that most of our winching when stuck in a snow drift or in slush on the lake will be very little strain in comparison to it's "tearing limit". Many times it's literally a bump to get it moving to dry/solid snow for traction and we are good.
