Hello, been reading a lot on this forum but just started posting. I have read several threads and watched several videos on DIY whoopie slings made from amsteel, and am wondering if when you thread the amsteel back into itself its possible to miss the center? or if any threading of the amsteel back into itself could possibly miss the center and therefore not have the same weight bearing capacity if that makes sense? basically what i want to know is if DIY whoopies are pretty easy to do and mistake proof, or if i should buy a set of whoopies to begin with. thank you
