Hi There
I also have the Slingshot 200AW now. I bought it a couple of weeks ago. Of the 3 bags I have (LowePro Nova4, Tamrac Expedition 4, Slingshot) I prefer it the most
I have my D70 with Kit lens attached, 50mmF1.8, 80-200F2.8, Charger, card reader, spare battery + AA batteries various filters, cloths, lens brush etc in the bag. Could probably fit another lens in the bag as well. I have the top section open for my soon to be aquired SB800, and the external pouch contains cloths, and a couple of odds and ends.
I really like the way that the bag can be carried like a backpack, but easily slung around to access the camera - this was a major bugbear with the Tamrac (with a proper backback, you have to find a spot to put the bag down to take camera out etc.
I think that a smallish size tripod could possibly be attached to the side of the bag, as it has a couple of fairly strong tabbed loops attached. Not sure if it would fit inside
Good Luck.
