Just picked up my '11 Bents.
179cm mounted at core center with Jesters.
Sorry if this has been done already, searchbar'd and couldn't find shit.
Here's some pics with my old ones for comparison:
Side by side
Carbon stringers? I think.
Height and side by side tip comparison
Side by side tail comparison
They seem stiffer and maybe a little livelier
A bit heavier, not sure you'd notice since the old ones weren't exactly feather weight either.
