75-80' sectionless wakeboard line?

A few weeks ago I was looking at a web site that sold their own brand of wakeboard lines. They had several kinds, but what I liked was that you could get the exact length you wanted, without sections.

I have a Skireel, so I don't want any sections - I just want a long line that I can adjust on the fly to the desired length.

Does anyone know what site I might have seen, or know of any 75-80' sectionless lines?

(I think the longest I've found so far is 68' with the Straight Line "Team Line" - http://www.slsports.com/wake-ropes-team.htm)

Thanks.
