It's difficult to say exactly as it depends on the rate of change of data within the linked clone desktops as to how much each one 'grows'. You'll have a single 80GB replica image, which all desktops in the pool share, and 10 delta disks, one per desktop, for the changes.
From a management perspective I'd go linked clones all the way. Say you want to install an update to your template and roll out the change to the pool. With linked clones you're only looking at one clone operation (Template to Replica) and then a Recompose of the desktops. With full clones you need to perform a full clone operation per desktop, which will increase the length of that task massively!
I run 800+ linked clone desktops in our environment and I struggle to see how I'd manage it using full clones.
