I have ridden the Jackal and LOVED the geometry! It manualled really, really well and just felt so good! I have ridden one that was built up at only 30lbs! It was built up sweet with a Vanilla, Chris King, Holzfellers, Hayes mag rear, Atomlab pedals, michelin tires, easton stem and carbon bars, and *I think* some rhyno lites. It was sweet.
