Foam is funny for me. I know the reputation for it being a pain, but 9 times out 10 it goes easy with no spinning or slicing, even with like 6/0. But then, with all conditions seemingly constant, that 10th time will be a huge pain in the ***. No idea.
Biots are kinda the same, but aligning biots is more consistently a pain in the ***. I'm probably closer to 50/50 on having a cool hand with them.
