I like 90 very much because of the way it depicts integration of the "w" and "m" into shape of a spring. The symbolism of the spring is appealing becAuse of what it says about energy being created and available. What some ppl have said is that the spring shape looks like barbed wire ... I don't know how you fix that but I wanted to provide that feedback to you to see if you could do anything about it... It is a very strong design but if you are able to answer to that feedback, I would be curious to see anything you can put together. Thanks very much!
