Use the creep tables on our website for setting the line size for creep. We have not seen any creep issues when referencing the creep tables to set the line size for no more than about 0.5 inches per year based on expected pretension. We have published numbers for ceep for sizes up to 13 mm but have in house numbers for line up to 23mm diameter. We also size for desired stretch. This is one of the differences from steel, stretch and/or creep are the limiting factors with polyethylene line so we need to design for them. Creep is relatively easy to design around but demands a little more understanding than when using wire. When sized correctly for Stretch and Creep Dux strength is usually at least 2-5 times stronger than 1x19 in the same application, so strength is the secondary (or tertiary) consideration. We can help anyone to size their line just send us an email.
If you want to do a backstayless rig we need to understand the pre-tension that you will need to size correctly as it will be relatively high.
