If you will only be doing shuttle stuff, a stinky will work for you because it sucks pedaling a Kona. they also have the one above the stinky i think...the stab? i dont know, i dont fuck with full suspension.
some will flame for saying this, but if i were you, and i were just getting into it, i would look into a freeride hardtail...for around $1200. Look at a Transition Vagrant, or build a p.2 like this...
you get a bike with alot less to worry about mechanicly, and the hard tail will make you a better rider, so when you do start to race, you can hop on a fully and ride smoother than ever.
