Letter of recommendation

[whiterabbit]

I'm applying to stat and biostat PhD programs. I double majored in math and economics in undergrad. Two of my letters of recommendation will be coming from math/statistics professors with whom I've both taken classes and worked for either as a TA or doing research, and I am confident that they will be strong letters. For my third recommendation, I have a trade-off I'd like some advice on. I can choose between:

• Economics professor who will write a glowing review about my analytical skills, but will not be able to speak to my quantitative skills
• Math professor who will write a good enough but not glowing review, but will be able to speak to my quantitative skills

I know the latter is the more natural choice, but I'm hesitant to forsake a glowing review for just a solid one.  Would I be shooting myself in the foot choosing one over the other?

This is a no-brainer to me: get one from the econ prof. You want letters that are "difference-makers", and it sounds like that's far more likely to come from the former than the latter.
