Tough one! I love my studs. Huggies are so pretty and Bev K''s look awesome. Plus you can add earring charms later which is fun. I would go for earrings for sure.
Okay so... I think I''d going to shoot for the studs!
The upgradable part is what did it for me. I get to wear them AND save up for bigger ones! How do you beat that! Yahhhhhhhhhhhhhhoooooooooooooooooooo! I''m excited. They will evenutally be great matches for the pendant (one bezeled). And I can get jackets to hold me over till then. Then use the settings and the jackets for colored studs after I upgrade. Loving it.
