I've got a few packages that I'd like to use bleeding edge versions of (gpsbabel for one, and maybe Firefox 4?). I'm assuming the newer versions will eventually drop into Testing, but I'm way to impatient to wait a couple weeks--I'd rather deal with a little bit of instability here and there for these couple packages.
Installing the packages from Sid is no big deal--I can just enable the repo, install the program, then disable the repo again--I'm terrified to run my whole system on Testing

. However, I'd really like to keep getting updated versions of those packages. Is there a way to enable the testing repo for those packages only?
Thanks!
