The Impulse is interesting. Looks like it uses the same coverstock as the Swerve GT, just factory finished with polish instead of surface.
They're using the same coverstock on the Tyrant that was on the original Swerve, but with the Hypershock in the coverstock as well as the filler. Stuff like this is always worth keeping an eye on to see if it's just hype or actual substance. Columbia 300 is due for a big hit in their high-end line.
