I'd like to get some feedback about what people think about polyester rigging thread. I realize it has both pros and cons. I'm working on a Mamoli Victory and it came with virtually no thread at all. Especially no black for standing rigging. So, I bought some .5mm black cotton prewaxed which seems to work well. Over the years, accumulated quite a bit of black poly. What I have came on both rolls and flat wrapped and seems to hold the shape of what it was spooled on. I actually tried running it through a flame to remove curls and kinks. That works pretty good, also managed to stretch it a little with no expected shrinkage. Thanks, Ken
