After doing the research we're of the opinion that for a portable course a steel cable mainline is really not necessary. We do realize however that some people prefer to use a cable mainline for a portable course rather than a poly rope mainline. Our stainless steel cable mainlines are built and designed to be useable for either portable or permanent installations, and will work with any of our three different buoy arm designs. The choice is yours. If you're going to put in a permanent or semi-permanent course, we recommend steel cable. However we do have numerous customers who have been using our poly rope mainlines for 3 - 4 years now in semi-permanent installations without problem. If you want a truly portable course that's easy and quick to set up, take down, and transport we suggest going with a poly rope mainline. For a permanent or semi-permanent installation we suggest going with the stainless steel cable. However, the final decision is yours. Won't a polypropylene rope mainline stretch? Won't that throw off accuracy? Yes, it will stretch a bit, but NO it won't throw off accuracy. Here's why. First of all it's true that poly rope does have a certain amount of stretch to it. That is the nature of poly rope. We factor that stretch (which is a known quantity) into every mainline we build and we guarantee our mainlines to be within and to remain within the dimensions established by USAWS and IWSF rules. ...
