Quote from Mentosftw;191878:
"Using a Tower Cylinder (which is currently unimplemented) [people were probably too lazy to edit this] will increase the freezing time by 1.5x."
Wind cylinder is up to 5 seconds I believe.
Wind Cylinder gets 6 seconds from upgrades, and a base bonus of 1 second for a total of 7 seconds. Or a 46.777% boost.
Tower Cylinders get said 50% boost, as well as a larger effect radius (?). But requires installing the cylinder and restricting movement.
I'd go with Wind personally.
