Can't you just have them both?

Sure seems like the best solution..
For the record: I've tried going after two sisters at the same time. I'm sure it'll work out better for you though.
Edit 2: Not my sisters. For some odd reason I felt obligated to point that out.
Edit 3: It's not like you even know I have two sisters.
Edit 4: I wonder if I've ever mentioned that I have a twin..
