For a mini survival pouch like I posted about before, Would you folks consider a space blanket or a disposable poncho to be the best addition?

There is only room for one or the other, not both.

I know each has advantages over the other in its intended use, but I am starting to wonder about which one would be better used in a short term situation and which would fit better in a mini-pocket pouch survival kit.

What do you guys and gals think? If you could take one or the other what would you take and why? Just wondering what everyone else's take on this is.

Thanks
