Changing Names: Rainey vs Toshiko

Everyone's knows someone who went through one of those phases. The one where they're out to change their identity.

Well, I may not be out to change my identity, but I do want a change of name.  I have a lot of trouble with permanent things. I like change, which is why if I get a body modification I make sure it's easily reversible like my tongue piercing. I leave it out for a day and it's like it never happened.

The only problem is I like drastic change and most drastic changes aren't easily reversible. I chose my name because it's an easy fix. Nothing permanent, but still really fun. It's not too far of a stretch because Toshiko happens to be my middle name. Whoa! But that's a Japanese name! Correct. 

I may not look Japanese, but I am. That is another post entirely, which I will probably address at some point in time. 

What I really want to know, even though it's not going to affect my decision, is which name sounds prettier/more exotic: Rainey or Toshiko?
