Carlfox,
Making these choices this early sounds like good planning, but is actually frivolous. College changed my perceptions and all math and physics grads in my degree turned out as individuals.
I don't mean to be rude, but it's sounds like you have an example of "Johnny down the road" syndrome, where you say "Johnny down the road did MFE and became a quant, therefore if I do that I will become a quant". That's the way Med and a small minority of degrees work. The way it works is that you do something you like and then start looking at the market as you leave, as markets will have moved on. Pitching yourself in a degree that has loads of options is also equally frivolous as if none of those appeal you're also screwed.
Thing about MFE is that you not only get limited options but alternatives are limited - many non-finance employers balk when they see MFE on a CV because they know before interview that you're using them to find a "gap job". Back in the day one would get a pub job (as I did) and keep applying for quant jobs. Also even when you get in, finance is the classic specialised job - well paid but as soon as things go wrong you can find yourself in an unemployable situation as you'll have no transferable skills to get into another profession. Many business bankers can get around this, but you never hear in the press about the maths guys that struggle as it goes against the media stereotype of bankers, but there's tons of them out there and even before the credit crunch there were plenty of math guys struggling.
And finally, don't do math in uni unless it's Ivy League or foreign equivalent. The difference is far more than reputation - many my MFE course weren't able to hack it having done maths and physics at schools that were below par and quant employers will know this. Also, you need top people skills to survive - many quants don't and get kicked out of industry or leaving due to stress within 5-10 years.
