I used one for years, I'd still be using it except that all the weight hanging off one side of me started giving me back problems (old age is so much fun) What I did was get a bunch of the "slinger" padded lens cases from Adorama, put my lenses in those and the camera in the middle worked very well. A bit of white adhesive tape on the top of the lens cases enable me to write which lens was inside the case. There are several benefits to this system:
A The lens stays in the case giving me good protection at home also.
B there is a nice sturdy velcro strap on the lens case, so if you are doing a lot of lens changes between two or three lenses you can attach the cases to your belt or the strap of the bag so they are quickly accessible.
I still use the lens pouches in my backpack style lowepro slingshot. Saves room in the bag and makes the lenses more accessible.
