Thanks for the entries. Great variety. Here is my 2 cents.
I like 29. It seems sophisticated. I like the different colors chosen. The swooshes that come through the sphere could be a little more exaggerated, maybe even have them trailing off beyond the edge of sphere.
#34 and #31 are nice too. I like the design. It kinda reminds me of a "D", so maybe something similar playing off the D in Dash could be cool. Maybe in front of text or going through Dash or splitting the words.
#33 is a bit too much like Nike. I lie #32 however there is a competitor in the industry that has a similar emblem so I want to stay away from the round, ribbon look.
