Peter,
Giant is using a true 4bar (lacking only in the horst link) but also using the swinger shock.

We will probably see a similar setup on the enduro in the next year or so
Scooby, you like the integrated headset? Most people especially freeriders, don't like integrated headsets as it tends to put to much pressure directly on the headtube instead of the headset. Just curious
As for my vote. No clue both are going to be similar rides, I don't personally know if *I* would need the swinger but it is a great idea
