Travel isnt everything, it's the geo of a DH bike that make them ride they way they do. I have ridden several of the Canadian DH parks on my 6" Intense and kept up with my mates of full DH bikes(most were specilized demos) the only thing that slowed me down was big rock gardens and drops.
But a full 8" travel is fun! I turned in to plow king on a DH bike because I didn't have to worry about the big stuff. Supposidy the Intense 951 small is quite compact but a little expensive.
