Not a fan of parametrics
Honestly, you don't even need
to bring up parametrics in your 1NC. Just run the counterplan and act like nothing's out of the ordinary. If they attack the CP for being topical, you can bring up parametrics in the 2NC; otherwise, you're home free. (You only need to bring up parametrics in the 1NC if you think your judge is theory-aware enough to get pedantic about topical counterplans without the debaters bringing it up, but not theory-aware enough to care about parametrics - which is pretty rare. It might be worth it for certain former debaters, though.)
If you do
have to justify your CP, and you don't have a very technically-minded judge, you might consider going for straight-up plancentrism
rather than parametrics. Stuff like "We should really consider the resolution more as a guide for what to talk about rather than a specific statement that we have to affirm or negate. After all, if a senator in Congress proposes an immigration law, it's perfectly reasonable for another senator to argue against it by proposing a better immigration law. That's a good, important discussion we should be having. The Affirmative's argument is basically like the first senator going: 'Noooo! I get that your plan is better than mine, but you're still reforming immigration, so I still won the debate!' That's ridiculous. In the same way, it's perfectly reasonable for us to argue against the Affirmative's plan by proposing a better alternative. We've proved that their plan is wrong, so that's all that matters."
Now, I think that's a terrible argument
and would relish bashing on it in the 1AR; but it's intuitive and understandable, so it's a lot more persuasive to most judges than some abstract theoretical framework they don't really understand.
