Strength difference between 8-strand and 12-strand Amsteel/Dyneema cord?

[MikeCD]

MikeCD, In one school math class, the textbook included the answers to odd-numbered exercises so the students could check their work. Problem was, some of the given answers were wrong. That taught me, "Just because it's in print, that doesn't mean it's true." That the person writing the description could make an error between 8 and 12-strand would not surprise me given the "quality control" of today's world.

That rant aside, as others posted - 7/64 is completely adequate. A more significant issue might be handling. The thicker the line, the easier it is for me to deal with. It is amazing what that small difference between 7/64 and 1/8th can make. A Button Knot in 1/8th looks gigantic next to a button knot in 7/64th.

Before you go full bore with the whoopie style, you might want to consider the UCR.

The UCR uses less material and can be made so it has a "lock" that tightens if it starts the slip. TensaOutdoors uses UCR's for the anchor line of their support structures.

I've switched to UCRs and I'm never going back! Thank you for that recommendation! I used tutorials by Tac Blades with one modification: I don't put loops on both ends of the long strand. I put a loop on the business end, and on the other end I just bury some of the cord back into itself to make that end thick as a handle and keep it from sliding into the bury on the short rope. I made a couple with too short of a bury which seemed to slip under pressure, but most of the ones I've made are working very nicely definitely save me some rope. Thanks again!

What poles are you using?

Right?! UCRs over Whoopi slings for sure.
The poles I'm using in that pic are aluminum military camo net spreader poles. I think they are the same as antenna poles. They are in 4' sections
But I've used a variety of things at this point.

Awesome, thanks!
