Loving this bag big time as it holds all my equipment outside of my Manfrotto 190XPROB tripod, 680 monopod, Cullman Magnsit ballhead, 2 Nano lightstands with umbrellas (am looking for a bag for these now), and a 5-in-1 circular reflector. The only bag better than the Tamrac Ultra Pro 13 is the Super Pro 14, which I'm having problems locating in Singapore.
