I started with simple Polygon tubes and thought I could get away with just putting a nice texture on them but that's not really going so well so I have residned my self to making all the rope on my HMS Victory WIP again

So with that I did a little search on the both the internet and on this site and the best I came up with was mhcannon's Make a Quick Rope (Part 1) thread but I am having poblems with it. For a start my rope is looking more like an umbilical cord than anything else. I like the twist but it's way too slack.
Please help if you can.
