Thanks guys. Do you know what, I have been on another site specifically for the outdoors asking the same sort of questions and got a little bit of the same answer but I think the repsonses here have been better. Elsewhere its been X brand is better (heavier and fussy) Y brand is lighter (v light but no back stiffener as meant for SUL loads). Kind of missed my point. I need a bit of a load lugger (up to 15kg) but about 1kg to make the 600g wieght saving worth it. All I can say thank goodness for BCUK. I now have the advice I need to go ahead with the purchase, which quite frankly I guess was always going to happen. It has too many pluses. Buy British, light, perfect back length, durable, simple single compartment, relatively cheap and made about 30 minutes drive for me in a direction I go about 3 times a week anyway so less miles (excellent carbon footprint for such a product).
Now I'm interested in the shovel pocket. I wonder if it could be done as a removeable shield type of thing. I reckon if it couldbe rigged to be taken off and put back on easily I then have the option of using it or not. I always like then as I reckon it could be used to stuff my tarp in as the last thing to be packed. Usually I pack my tent in the back of my sakc which means not packing it until the tent is pitched. Now I'm into tarping the tarp only uses trekking poles, guys and pegs so I could pack it last thing into a shield type compressor pocket on the front of the sack. It might even dry in there too if the rain stops. Hmmm! I wonder what weight that would be. I reckon another talk to them at Aiguille with a few sketches of what I want.
Thanks guys. This site truly rocks!
PS where do you get that smilie that says "you rock.2?
