Which tile would you eliminate? (A shameless rip-off thread)

[AdrenalinDragon]

An all-purpose force floor would more likely be one that changes direction at the push of a button, as I believe J.B. mentioned somewhere earlier. It could be a single tile that rotates between 4 directions or a strip that changes between 2.

Didn't they have that in Chip's Challenge 2? I mean, the official unreleased sequel of course, but it was train tracks instead?
