I have judged for high school debate tournaments for 10 years, and genuinely enjoy doing so. LD is by far my favorite event, because it is so beautifully structured, and requires significant thought and preparation and analysis.
In my day job, I'm a lawyer, but not a courtroom litigator. I'm not impressed by snarky CX strategies or ad hominem attacks during rebuttals. Your goal during CX & rebuttals is either to clarify information provided or to poke holes in your opponent's arguments, not to show off how clever you think you are. If you are in fact very clever, it will be evident to me based on your questions and arguments during the round.
I am a traditional flow judge. This should be a value debate. I want there to be a good clash, and I want each debater to have sufficient contentions to support his or her chosen VP/VC (so a kritik will probably turn me off). The evidence should be legitimate, and it should link to the contentions and then up to the VP/VC/resolution without me having to twist my brain sideways to figure out the links. Don't spoon feed me, but DO make sure it's addressed in your framework, because I won't assume a link exists if you don't mention it during the round.
The number of contentions is less important to me than the strength and validity of each one. It's possible to argue a winning case with only two contentions instead of nine, as long as they're well-researched and well-presented with great links to your value structure.
Also - even though I'm flowing your arguments, it's not an all-or-nothing round based on the flow. I'm definitely NOT persuaded by a debater who says "well, my opponent dropped my 4th contention so that argument carries through the debate and therefore I win the entire round" - because maybe your 4th contention was so worthless your opponent didn't see any need to waste time refuting it (for example). My point is, you won't lose just because you fail to rebut every single point your opponent makes; and you won't win just because your opponent fails to rebut every single point you raise. I'm flowing your cases, but my decision for each round is not limited ONLY to the specifics of the flow.
You will impress me much more with quick-thinking analysis of and response to your opponent's arguments than with a well-written constructive case (although the latter should be a given at this level of competition). I am not, on the other hand, going to be at all impressed by esoteric theoretic non-topical pollutificationism (although it can be entertaining, it won't win you the round).
I am able to understand extremely fast speech as long as you articulate your words clearly and remember to breathe. That said, IF YOU SPREAD - I WILL PROBABLY DROP YOU.
