Ti is my fav - obviously since I own 5 - but the GMZ is gorgeous. I have however decided she will stay at home now. I had her at work and nearly dropped her - in my frantic panic to catch her before hitting the concrete - I think it pulled 3 disk but she never hit the floor.
Oddly, I have dropped my Ti a time or 2 and it doesn't have the first mark on it.
I can't handle the stress of worrying if I drop it at work so now if I take the GMZ out with me, she goes in a leather holder.
My second fav is the SS - though I don't own one now.
