I currently have a Lowepro 350AW , but its not fitting all of my items. So, Im looking to get a new big bag, which can fit all of my items. Here is the shortlist : Lowepro x200 Pro Roller Lowepro x300 Pro Roller Think Tank Airport International Vanguard xcenior 62T Kata FLYBY-76PL Help me choose one from the above list, which is real big and can handle any amount of gear. I need to place an order today, so please let me know . __________________ I have : 5D Mark 2 , 17-40mm L USM, 70-200mm f2.8 L IS USM Mark 2, 24-70mm L USM, 100mm f2.8 L IS USM, 100-400mm L IS USM, Benro big tripod, Canon 580EX 2 flash, various filters, macbook pro, iPad 2, iPhone 4S white. ---------- Im getting a good deal for Thinktank Airport security v2 : http://www.thinktankphoto.com/products/airport-security-v2-roller-camera-bag.aspx I was thinking, if I can settle for this and also another big question is : Is it okay to send this as a check in baggage ? I mean, I never send my camera goods into check in, rather I always carry with me into the cabin as cabin baggage , but since this is ultra big, I dont have a option. Just need to know, what extra measures can be taken, if we are sending this as check in baggage, so they airport guys dont throw it here and there into the plane logistics box or the delivery roller lane. Let me know.
