I’ve used synthetic winch rope for many years, as in 15 or so. I was the product manager at Ramsey winch to introduce synthetic rope for their off-road winches. I thought I would use some Dyneema rope for a couple projects. First, I made some straps for my trailer to tie down the front axle since I have limited space for the connection point. Then I made some soft shackles using an improved splice that cannot come loose. The breaking strength of these shackles is rated at 230% of the ropes breaking strength. That puts it at over 40,000lbs of pull to break the shackle. I used my hydraulic bender to tighten the splice.
