I prefer rope to straps any day. Rope can be re-looped, tied, taken apart etc without the need for special repairs. My static lines are 3/4" spectra. My dynamic lines are 2" poly.
I worked with a company deploying massive bouys, I just welded them but when they launched them somehow they told me I was the rigger... ZERO experience rigging these massive loads on a crane. I was given a credit card to purchase all the equipment and I went with all spectra lines. That stuff is insane strength for its diameter. (I know this from fishing) 200 pound spectra fishing line is like sewing thread.
When I was working offshore the guys on the other hitch had needed shackles with a 6 inch opening, so they ordered 4, 6inch shackles. (pretty much anything on the want list got delivered no questions asked)
Trouble is a shackle is measured by the diameter of the pin, not the width of the opening
We got off the chopper that week and looked down on the deck, there was 2, 4x4 pallets, each holding two huge shackles(each with a 6 inch diameter pin).
We were wondering what the hell are we gonna have to lift with those things! (they would have picked up a battleship)
