Hi I am very interested in buying a new camera bag. I recently went to a wedding that was shot by one of my favorite local wedding photogs. Shes awesome.. Anyway she was carrying this bag.. and she looked so mobile... I feel weighted down mostly.. Well I asked her and she said it was a shootsac., http://www.shootsac.com/index.asp?PageAction=Custom&ID=1 Anyone use this? I'm thinking of ordering one.. They are pretty pricy... I would like people to tell me if they are using it what they like or dislike,,, Thank you !!
