Hello Dennis,
One idea for a little variety is to delete the circle and wave and just have the cluster of bubbles rising from the last (i) in fineline. The dot on top of the (i)could be one of the bubbles.
If you think this would look ok please feel free to submit it .
I am getting a couple of friends to vote on their favorite logo so everybody still has a chance.
Thanks again for all your great designs.
Best wishes
David
