Sled Pulling Rope Length and Diameter

I want to get a rope for my prowler for rope pulls. What is a good length and diameter?

Get as thick and long as you can afford.

You could buy some 2.nd hand morring,if you live near the sea/ships.
Thick, durable and cheap.

I bought the 2" 50 ft length rope from Elite FTS. It came w/ a d ring to hook to a sled/prowler.

I looked for this but could not find it. I may have just missed it Do you know if they still carry it?

2" and 100 feet or more.
