Nantes to Palermo tour 2009

Really? Mine starts to go black with mold inside the tube after amount a month hence why I clean it every time I us it.

It's always the tube that goes nasty. It clearly works for you it's just I've never spoken to anyone who does not have the tube go moldy after a while.

I've never had any problems with mine going mouldy. Always just used water and always hang the bladder by the bottom in the laundry so it can drip dry. I still wouldn't like one for touring though. Your back is very useful for loosing body heat during hot summer days and plenty of water bottle options that allow easy water access without loading your body up.
