Thank you all for your replys. I didn't like the Unisons when I first got them and tried them on Canson. After using them on La Carte, I love them. I have a pretty good selection of schmincke and unison, so they are my main pastels for now, but I tried some senneliers and the colors were so vibrant, I didn't see that vibrancy in any other line so far. A friend sent me a few Diane Townsends to try and they are great, but very expensive. Thanks for all the help.
