I faced this problem a few years ago. (Whether to do a business degree or an IT degree, both were the same length). I ended up choosing business because I thought I'd get more out of it at university - I believed I could learn a lot of the technical stuff myself as there are lots of high quality resources out there. I think this has worked well for me.
Ultimately, one thing to keep in mind is the idea of closing doors. We all want to do everything, and our thoughts can picture us doing many things, and enjoying them. But unless you act and jump into something, as opposed to keeping your options open by dong this and that, you won't come particularly great.
Hope that helps and good luck!
