Kata bag experiences

I'm looking at a bag for overseas travel and looking at a couple of Kata bags.
The HB-207 and BP-502 that online look interesting, unfortunately I haven't been able to find anywhere in Adelaide (or Melbourne as I'm over here at til tomorrow) that carries much of a range to actually see and try them.
So, any good / bad experiences with either of these .. any suggestions etc?
Looking at carrying a laptop, D700, 14-24, 24-70, 70-200 and 300 f4 with a couple of other bits and pieces. And maybe a smaller day-style bag for general use.
Cheers
Tom
