I buy from Fleet Farm - Atwood Rope Co. brand - we buy 300 ft rolls of 1/16 in for about 6-7 bucks, some is not hollow - it has a core. (the rope without the core seems to tangle easier) It's the stiffness and ease of tying different knots that don't slip that I like. I have to assume their other ropes can perform as well.
This isn't super-strength, "only" rated at 85 lbs.
