Fred I have also heard this before where some companies [not saying all] will reuse incorrectly dyed color threads for black. I know when we used rayon threads, we found that the black tended to be weaker but since switching to poly, haven't really noticed much difference between black and the other colors. As far as having more thread problems as you get closer to the core of the spool, we have never run across that. We use / have used Ackermann, Marathon and Gunold threads and try to use the spool right to the end [or as close as we can get - depending on the design]. Bob .
