I love both my Goblin and Griffin, and the third Airborne frame is being built as we speak (which is scheduled for release later this summer but I know nothing about that... )
The Griffin is just flat-out crazy fun, and eats the sandy trails up here in the desert like it was purposely built for it. Since there is so much contact patch with the bigger 3" tires, I am actually much, much faster downhill on this bike, but only a slight bit slower than the Goblin on the climbs. I can hit 36mph on the Seven Sisters downhill section, whereas on the Goblin I am lucky to hit 30mph. Since that pic, I have shortened the stem, and cut the steer tube, so it just gets faster and funner!!
