I really like 162 and 126. The colors for 126 we especially like. 164 and 163 don't quite work for us. The only problem with 162 and 126 is it doesn't show community (like you are trying to do with 164 and 163. Don't know if it is possible to reconcile this need.
Here is our need for the logo to convey: global community focusing on performance.
Thanks for all your wonderful efforts here.
