I currently have a Lowepro Slingshot 200AW, Flipside 300 and a Pelican 1510 Medium Hard Case. For an upcoming trip to Hawaii, I want to be able to bring my 5D2, a 70-200 2.8L IS, 17-40 L, a 50 1.8, and my iPad (I was thinking of the 24-70 as well, but decided it would be too heavy to slog all that around the airports, and I don't want to check my gear -- don't trust the airlines). None of my current carry cases will work so I was looking at the Streetwalker HD. Any current owners care to comment or offer up an alternative? Thanks.
