I think for the most part, students and judges like the additional minute of prep as well as the additional minute to the Summary. This has extended the length of PF at tournaments, especially ones with double-flights. I would recommend that the first 2 Crossfires be between all 4 debaters and that Grand Crossfire be eliminated. This would cut down on the length of the debate back to the original time – would preserve an exchange between the debaters in a cross-examination process, this would be good for novices who may or may not be comfortable asking or answering questions by themselves, all 4 would be encouraged to be involved, and if the 2 that just spoke wish to clash, they can.
Also, Roll Tide!
