I have 2 - 150' lengths of Black-Max.
Decent rope for the money you pay to get it. It ties knots just fine. I honestly don't think you will be able to tell the difference between Safety Blue and this rope in question.
The rope may be slightly waxy to the touch, but so are most new ropes.
The only thing that I didn't care for was the fact that the outer sheath had a lot of stretch in it....................therefore, if you don't milk the excess off of the inner core, you may find the sheath bunching underneath your attachment knot. However, once milked, the rope is fine.
If you aren't familiar with rope milking, all you have to do is tie one end of the rope to a solid structure, like a tree. Tie on your favorite friction knot...............perhaps a Blakes or Tautline.................lean back and slowly let slack through the knot. You will find that the sheath will to begin bunch. Milk the rope all the way, until your knot falls off the opposite end of the rope. Repeat until all stretch is gone.................then, the rope is great.
I personally have gone to Blue Streak with eye-splice.............high tensile breaking strength and no excess bulkiness!
