Hi guys.. would like to hear from you. I packed my gears in my flipside 400aw (Canon Xsi gripped with Tokina 50-135 f2.8 lens attached, Tokina UWA 11-16 f2.8, Tamron 17-50 f2.8, Tamron 90mm f2.8 macro, Canon 50mm f1.8 and speedlite 430ex, dust blower, lenspen and CPL/ND Flters, charger, cords, extra batteries and memory cards, and a 10.1" laptop). Attached to the backpack is a standard tripod. Do I miss something important? A bit heavy though but feels comfortable. This will be my first travel in China and hope I wouldn't regret not bringing one. Thanks guys
