CS or Stat major to supplement finance + econ?

I am entering my second year of undergrad and plan on specializing in Finance and Economics (BCom). I'm interested in doing another major, but I'm trying to decide between computer science or statistics. Right now, I am not completely sure what I want to pursue specifically concerning finance, but I am considering becoming a quant or something that would also integrate CS/statistical work and might require me to go to grad school. From the research I've done so far, some people believe statistics is very specialized and would not be beneficial, while others say it can supplement a degree in finance. I've also heard similar things about a CS degree. I enjoy both CS and statistics from my own experience, which is why it is so hard for me to make a decision.  If people have experience with either degree or believe one would be a better supplement to finance and econ, your input would be greatly appreciated!!
