#25: The best of your four initial options. The symbol is interesting. Perhaps slightly smaller and offset where the point of the grey triangle is between the E and L. Both triangles would move the same amount. I would like the symbol to somehow relate to the company with a verbal description, not sure how this could be done. #24: The diamond shape is no tidal. #23: Too busy. The O looks like the Polaris logo. #22: Symbol is too busy.
