ok update got the bag in so far i like it this is what it will hold with still more roome!!
this is the bag from a side view fully loaded (kinda eavy but seems worth it)
Standing up no bigger then a camel back!
and everything inside Nikon D90 18-105VR, 35mm f1.8, Sigma 50mm f1.4, hoods for all 3 lens's, sb600 , shock pump, Tire pump, spare inner tube, allen wrench kit , tire levers, 2 wireless trigger 1 transmitter, and a patch kit, and a 2.5 liter bladder... there is still plenty of room for food and other random items, there are plenty of pockets for memory cards etc.. I really like it so far will update when i take it for a ride....
