I'm in the process of doing research and to purchase a new backpack for my LF ca mera and my main concern would be comfort of the pack while on my back with it l oaded down.I hate to spend alot of money on a pack and find out it is uncomforta ble and hard to carry. Does anyone have any suggestions on a good quality brand name that will hold up with regular use and that you would highly recommend. Tha nk you in advance for your responses.Robert C.Warner
