I FMQ in metallic all the time and second Superior. I use a 50wt cotton in the bobbin. You'll be surprised at how low you have to dial the top tension to get it right. I recently tried Superior's Titanium needles - size 14/90 and quite liked them, although I'm not sure yet if the extra expense is justified.
The red is a Superior gold - the photo doesn't show it, but the white is also quilted with an iridescent thread.
