When you want to use gigabit ethernet in the future for example, you will need all 4 pairs. With the increasing number of projectors per show, the likelihood you will need gigabit someday is increasing as well.
Between the switch and the projectors, 100Mbit will do just fine, but between PC and switch and inbetween switches, I would use gigabit.
I don't have a crystal ball to look into the future and guess what pangolin (or anybody else) will do, but that's what I will prepare for when making / buying new stuff.
