I might be going to japan in june as a school field trip, and i dont know whether to bring my vanguard kenline 59 or get another 'the bucket' for my complete seed. Im gonna bring my 40D w/grip, 18-55, 20-35, lensbaby muse w/ 2 more optics ,a tripod and my macbook alum. is it too many things to bring? So which bag will be more suitable? TIA!
