41 years old is almost impossible to be accepted to top 10 business schools. I think your goal is unrealistic if you are trying to break into asset management at such age. There are plenty of applicants with higher GMAT, younger, hungrier than you gets dinged everyday.
But that's just my opinion, you are certainly welcome to try.
I didn't bother to read everything above. I apologize if I am saying anything repetitive. I am in NY and I have managers (very bright ones) who did not want to interrupt their careers and attended NYU PT MBA, NYU EMBA, and Columbia EMBA. I know some people " just pay" for an EMBA, but it is unfair to make that generalization that EMBA programs are bad. Because of your age, and accomplishments, EMBA just makes more sense because over there you will study with and nework with people similar to you! Imagine you sitting next to a 24-year old HBS MBA who wants to do consulting after his/her MBA... you would be... kind of... out of place.
MBA is for people who want to switch careers or enhance their careers. You definitely CANNOT play the "switch career" card. Jobs in finance are tough now and for years to come. So right now for the people who want to do post-MBA finance career, the "finance programs" tend to look for people with previous finance experience. Taking a career switcher is risky... and taking a 40+ year old switcher is extremely risky.
You will have to play the "I want to expand my network" "improve my soft skills" "return to my previous job to enhance my career" card. Throughout your application you will need to show adcom the value you will ADD to the MBA program you are applying (whether it's your entrepreneur background, management skills, ability to hire people with your company, ability to succeed after your MBA program, etc).
Now talking about the "age friendly schools." My thoughts go to Yale, Duke, Cornell, Kellogg, Tuck, Berkeley, maybe Wharton (notice Wharton has a new dean who wants to have younger applicants and they reduced avg age from 29 to 28 for class of '10 to '11). The "finance schools" tend to take younger people.
