I've never used the stuff from Goodwinds, aside from their Kitespar, but it looks like it should be fine. Most people use 1/2" diameter stuff, so their stuff is a little on the thicker side, but not considerably so.
I've heard good things about the stuff from
Max Gain Systems.
Fiberglass does vary a tad from manufacturer to manufacturer, but just about any of it works. It becomes more of an issue when you're working at the max length of a core's effectiveness, like with min-reds on 1/2" or min-glaives on 5/8".
