The way "points of information work" is pretty much, the person stands up and waits for the speaker to recognize him. There isn't any verbal interruption, and frankly, most judges find verbal interruption to be super rude. There are "point of orders" but they're different and the best thing ever. We've all probably experienced rebuttal abuse, and "point of orders" exist so people can appeal a misrepresented argument or a new argument in the rebuttal. This actual allows for a fairer debate to take place.
I'm a second year debater in STOA that's done decently in both TP and LD, but I've found that parli has been the most beneficial form of debate. Parli is more real world in that it's more conversational, less structured, and teaches kids to think off of their feet as no prep time is allowed. It's similar to a coffee shop debate that one would find himself in when he isn't in a suit.
No one is going to start sorting through briefs and reading cards in their local Starbucks. But people still discuss issues and look to the common man warrants.
Also, (at least according to my coaches) parli is the most common form of debate in collegiate debate. So if you are thinking of that for the future, parli debate now is pretty beneficial for the future.
The best parli debaters are the ones who are well versed in many topics/formats. And yes, even past extemp (though extemp helps in parli). Some of this year and last year's top parli teams like Ortiz/Pena, Marton/Winchel, Chapman/Heise, Bakke/Hillery, and Kendrick/Kendrick are super good because they are well rounded in things past simply "current events" or their "debate resolution." I'd partially attribute their success to active learning in other realms. Also, parli teaches values and policy theory, making transitioning formats really easy.
I had originally planned on doing TP this year, but half-way through pre-season, God decided to close the door on that. It wasn't to hard for me to transition debate formats because of parli. I still don't like LD (Evan knows this haha) but I can at least not die because I understand values.
Most of the people I've found who don't like parli are the ones who don't try to learn anything past what they are comfortable with (ie. LDer who only likes values). The ones who enjoy it are the ones who try to grow with the differences in the format.
Obviously, this is going to be NCFCA's decision, but I'd urge you not to discount parli without trying it out, whether it be at a tournament, summer camp, or with some friends.
