Thanks for the quick response to our reactions. It really gets better. Some new reactions. The line in #9 looks great. We also like the weight and color of the text in #9. We are not sure about the position of "&". Maybe this can be positioned differently or somehow in the background, but bigger. Not sure how this can be done, but maybe you have some ideas. The "p" in line one should be more away from the "l" in line two. They are connected. We would like to see the text being slightly farther from the line.
The pions have a very classic style, maybe it would be an idea to see some other style in the pion shape. The ring in #6 is not bad. Maybe there should be a fourth pion. And/or a more asymmetric positioning, where the small one is more to the right.
We disagree about the ties within the group. Maybe we could see some with and without.
Thanks!
