My preferences for public forum debate are as follows... 

I want to see clash and impacts clearly. I would like to receive LOTS of analysis and explanation with contentions and cards. During speeches, I expect proper decorum and respect for your opponents, especially in cross examination when directly speaking with one another.  During summary, I would like the round summarized not another rebuttal and then strictly voters in final focus. I want to see the big impacts of my vote and what ¨the world¨ would be like if I voted in affirmation or negation.  

Win the flow. As simple as that.

In terms of your constructive arguments or "original case":

I don't mind "creative" contentions so long as they are properly supported. This means that your primary contentions only need to be tangentially related, so long as you provide a cognizable link to the resolution. It is your opponent's job to raise a valid defense, call irrelevance, or reframe the more important arguments.

This gives you a lot of freedom to implement "more interesting" arguments. However, this is not a pass to present truly abusive or wholly non-topical arguments.

In terms of responding to your opponent's case:

I will vote for whoever wins the flow. Therefore, I like when debater's roadmap clearly and give explicit voters. I don't count roadmaps against a debater's time so long as they are less than 30 seconds.

I will not flow an argument in your favor unless you tell me why I should. Conversely, if your opponent drops a contention completely, I won't flow it in your favor unless you tell me to. I firmly believe that it is the judge's job to flow all arguments, but it is not the judge's job to debate/argue in their mind for you.

Speed:

I personally cannot handle that much speed. I can listen to you when you talk a little fast but, keep in mind a judge can't flow what I can't understand. If you choose to talk fast you have to enunciate your words. If you are talking too fast I will say clear. If you choose to continue at that speed I will say clear again. If I still am unable to flow and understand you then I will drop my pen and stop flowing until I am able to understand you.

Logistics:

Pre-flow before you come into the room. Keep your own time. If you don't already have the time constraints and speech order memorized, make sure to write it down before we start.

Cross-examination/Crossfire:

I don't care if you sit during these. In PF, I prefer teams to alternate asking and answering questions (unless it's a very brief follow-up). If not, a lot of unnecessary time gets taken up by asking/negotiating who is going to take the next question.

Have fun and be civil.
