Camera Bag Advice

I now have a sigma 50-500 and a Sigma 17-70. coupled with my K20 with grip I'm now looking for a camera bag that will accommodate this set up. i already have the Lowepro Slingshot 200AW (which may well be up for sale very soon)

any recommendations chaps and chapesses?

I have the Flipside 400 which will take my K20 with the 150-500 on or off the camera, several other lenses including the DA*300 and all sorts of other stuff. It has a waterproof cover and is comfortable enough to wear all day.

cheers Oggy. i thinnk this one could be spot on.!!
