It's time for a new pack. I have had nothing but great experience with everything I own from Zpacks. I haven't completely ruled out the mesh pocket on the Blast/Haul but at this point but am leaning more towards the zip. From what I understand the only design difference between the zip and the zip haul is the fabric? What are your thoughts on the Arc Zip in cuben vs dyneema? What is the different in water profess between the two?
