Hi wsaalum,
A 720/Q44 is an outstanding score (it's above the 90th percentile overall), so you should apply to any Business Schools that interest you. Barring a REALLY rare set of circumstances, there is no reason to retake (and that 'rare' situation would be if you were applying to an ultra-competitive Finance Program - in that situation, the Q44 would not 'impress' anyone - it's still a reasonably strong score though, even though the percentile doesn't show it).
Since you've named some competitive Schools, you might want to discuss your overall profile and applications with an Admissions Expert. There's a Forum full of them here:
