Sling type bags???????????

[UUilliam]

I'm in the market for a new bag...

I have used the slingshot AW 300
but was wondering, is there any other sling-type bags?
I am open to over the shoulder bags too.

requirements?

fit:
2x Cameras (1 with lens attatched)

4-6x lenses
Extra space for more accessories.

plan on getting a 70-200mm so...

advantage if it fits a laptop too.

the Pro runner AW 400 seems best so far as it seems the largest but... not a sling.
