Hi all, again about PS :P

So to be honest, I have not decided to pursue which field yet...I'm interested in a couple, but have not chosen yet. I thought I want to decide after I enter law school, so I am choosing law school which have both of the fields that I am interested in.

So I am not going to talk about why X field in my PS, but when I read some samples, it seems people have legitimate reasons about which law they would like to practice. (and I understand it because it would be one of the reasons they choose the school.)

If I do not indicate one, would my PS look weaker? I may want to honestly say "I have not decided yet" but would it look bad?

Should I just do more research and decide which one before I even apply law school?

Thanks for your insights.
