I like the shadow in #5, but I'm not sure about the symbol
I like the gray and orange in #7 and I can see that there are 2 'i's in the logo, but the i's look like they have funny tails... could you try that linking i's again, but a little differently?
Thanks for the new design... I like #65, but could I see the the logo "flipped" so that it leans to the right instead of the left, I think that would make it more interesting for me.
