Use Clone or Transporter or ...?

Leopard 10.5.2, Parallels 3.x running 5284 (the Leopard-compat build), XP SP2 installed on Shared, everything fine! (knock on wood).

Now... I want to install one or two more VMs on this same machine (or on an external), all using XP, but with different apps installed.

I've been puzzling over the forums and manual and can't figure this out. Do I clone the good install? Use Transporter? Use "New" and have it dupe the existing VM (assuming that's possible)?

I won't be running these at the same time, just quitting out of one and starting the other as necessary. (I assume you can't run them concurrently anyway).

Thanks for any help!
