Zpacks Arc Zip in cuben vs Zpacks Arc Haul in dyneema?

[lukabrazi]

I decided that I am going to order the Zip Haul in Dyneema as well. Did you get any add ons? I am considering the hiking pole straps and a belt pouch.

I ordered a dyneema zip yesterday and I asked if I needed a pack cover and was told no but to keep sleeping bag in a dry bag as a precaution.

Currently in the summer I use a 3/4 length zlite pad and then use my current backpack under my head and shoulders. I could save weight by getting the Arc Haul Zip but would I have to then start carrying a full length pad which would cancel out the weight savings? I guess my question is, is there any reason that I couldn't use the Arc Haul Zip as part of my ground insulation in the same way I was previously using my Osprey Talon?
