Hi Snappers
Thanks for your replies.
The main problem is that i have quite bad A.S(ankylosing spondylitis). So i get really bad shoulder ache. I really would like a bag with good padded shoulder straps, i think i would need to carry as least as possible too.
The Tamracs look like the have more padding on the straps.
I will try and get a look and feel of a couple before i take the plunge.
Buying a 100-400 won't help my A.S either
