I really like the M inside the ball. The lettering is ho-hum. I would even go for an all graphic logo with no words if you could incorporate all three letters and the flame.
Thanks for the updated entries. I think #10 is still the best. Thank you for going more abstract, but I must say I do not quite understand the new iterations. I like your ball and would work on that. You are different in that you are the only one that is NOT using a purple or blue, and that is not a bad thing. Perhaps just continuing with your first attempt is best?
I know I have this in five but I want you to know this is very hard. All of the entries now are really hitting on things I like. Overall your is just different. Its subtle. Like a letter drawn in viscous oil. This may continue to grow on me.
