Very nice logo BTW, and very evocative of Roger Dean's style.
I'd make both As the same size as the MIG and have the line cutting through the whole thing distort the letters a bit, like on the Psygnosis owl logo, the line passes through the 'I' and there's a diagonal cut into the letter.
That's a pretty bad explanation, check the picture here:
