I agree! I started with the 125 and broke down and got the 126, too. The MA told me that they designed the 126 especially to use with the studio sculpt bronzers. The synthetic side helps to pick up and lay down product since the powder is so creamy, and then the natural sides helps to buff and blend everything. It was a superior application of GR using the 126 than any other brush I have. I found the brushes to be pretty, soft (esp. the 125), easy to work with, BUT I do think they're pricey for what they are. If you have something similar, I would skip.
