Which Sandstone style should I get?

The leather isn't that light IRL. It has a hint of grey that should hide dirt. I think mine will be quite durable, you shouldn't have any problems. As far as too light for the big size, I don't think so. I prefer the part time style, but I think the work will be beautiful.
 
I would go for work style as it is large enough to stuff lots of things (which is very versatile and i like the size)....i don't think the color is too light as compared to white, etc
 
Well, I don't really use any of my shoulder straps and since I already have a PT I'm going to get the Work!!!!!! I'm so excited! Now, I can cross one style off my want list! Thanks to all of you that voiced your opinions!
