Hi Alf=red,
#67 and #54 are probably the best, IMO. I do like the creativity of #65, but don't think it will work for me.
I'd like to move away from the Recycle concept for the symbol. At this stage, I'm looking for a Reload or a combination of a Reload/Power Button as the symbol to the left or right of the logo text. If you use Firefox, and bring up a page in that particular browser, you'll be able to see the little Reload button in action -- that's sort of a nice representation of what I would like as a potential symbol. Unless you present something else that you think would be way cooler!
However, the logo I've currently ranked as
#2 in the contest, is the best logo in my opinion (minus the symbol creative). It's professional, crisp, and has a nice effect coming off the 'T' portion of the text.
Hope this helps!
Thanks,
Brian
