Anakiwa,
I'm in exactly the same boat as you--35 getting married this June. I'd always assumed I'd change my name when I married but now I have a serious professional profile in my maiden name. My final decision was based upon this: I love my husband to be more than I ever loved my father. So I'm changing my name. Also, I think if you are planning to have kids, it's nice to spare them the hyphen problem or the choosing option.
