I'm not an expert (others may correct me here) but I only use Schmetz 75/11 (now I don't know what it means by size #11) for embroidering ribbon.
On the puckering, i'm not sure either if it has to do with your needle. I do know it's all in the stabilizer and tension. You hv to play with your knob tension (it should be in your manual which way to go/turn, decrease/increase). I found that the factory setting doesn't necessarily means it's the correct tension especially on the embroidering.
I'm not all that. I just like the last part.
