If they look safe and good to use, they're probably good to use This is why we don't take angle grinder guards off Big grinding stones for pedestal grinders - not worth taking chances with - but small sub-5" cutting/flap discs... not really much kinetic energy stored there.
+1 on all those brands Moose mentioned. The daddy of abrasives for me is Pferd, but they aren't cheap. Klingspor is my second favourite.
The Abracs look decent, but we'll see how they actually hold up compared to others. Even at £1 each if they only last 30 seconds it's not worth it when good ones can be found cheap too. I've used Bosch a lot before and they last pretty well. I never remove the lawyer guard off my grinders, you only need to see one disc explode to know why they're there. I never quite understood why people remove them anyway.
Forgot about Pferd. I have a lot of their carbide burrs, which are excellent, and also got them all for ~£5 each by piecing odd ones together to make quite a decent set. Never used their cutting wheels or abrasives though. I'd like one of their diamond-coated wire wheels for removing mill scale but they're about £300 apparently.
