I agree with the previous poster - if you don't want to go there, don't apply. I know that sounds simple but that's because it is. There is far more to school selection than just their ranks.
With your stats, you should have a decent shot at multiple programs in the top 10. You're a little light on the professional experience side as well as extracurriculars so I don't want to mislead you there. Don't get me wrong, they aren't bad - just not exceptional. And for the top 3, they generally look for exceptional.
However, with your GMAT - jeez! Apply! Congratulations on absolutely crushing it!
I think for the purposes of this post let's bifurcate between "lower ranked" and "safeties". The range of schools that would qualify as your "safeties" aren't true safeties. They are merely of a slightly lower rank. But I think you could easily diversify your school selection to mitigate risk and still stay in the top 10. If you wanted to add ONE more in the double digits, I would recommend Darden. They are really strong in finance and their case method would be helpful in giving you the foundation for a corporate strategy position.
This is your decision - it's a personal one. You're already applying to the top ranked programs in the world, if you don't want to apply to a particular one, don't. Your subject for this post leads me to believe you think Columbia is world's beneath H/S/W. It isn't. If you look at the spread in points assigned for rankings, the top 10 programs generally vary by fewer points than you think.
As a side note - while you can wait to R2 to apply to some schools based on how you do in R1, understand that your R2 applications will have to begin the moment you hit "submit" on R1 apps. You will have to work on them as if you're still planning on applying. If you get acceptances before, you can always pull the plug. Just something to note.
I hope that helps - you have a great list of schools to choose from and you will be incredibly happy and successful wherever you go. Just make sure it's somewhere you WANT to go
Good luck mate,
