I'm trying to convince my dad to get back into mtn biking and the prophet is the bike we are looking at because a friend of ours runs a shop that sells em. Anyways I'm trying to find out the major differences between the different model lines to determine the best option. Even though the bike is for my father, I will be riding it more then him. I've already got a SC bullit for the heavy duty stuff so I'm not worried about doing drops on the prophet. Just looking for a nice trail setup.
