#39. We want to be able to use the logo without the character, when necessary. In other words, the chef/character won't always be present. That said, #39 makes this difficult to do, although it is a very attractive logo.
I like #41 because we can use "Jack's Flash" without including the character. That is great. I also like #64 because the "Jack's Flash" is more prominent. Can you make the logo bigger on #64?
