How would this bag hold up to rain? I know it doesn't come with a rain coat but heard nothing of it water repellancy .....or if you were to get caught out. Be nice to hear that the armour also was insulated with some type of plastic to keep water out. Being its such a great bag. Also wondering how flexible it is and if in fact it handle a 40D with a 70-200mm F/2.8 lens attached by altering the dividers. I have been looking for a sling that would and this seems to be the only one that comes close unless I went for the lowepro but then I'd have alot of unwanted space and flop. Surely there is a bag that can conveniently carry a full size body and good size telephoto with another wide angle for a day trip then going over board?
