alright here is the deal. sold my 4300 and need a upgrade, willing to spend around $850. i think i've narrowed it down to the 05 hkek and the 05 tassajara disc. i like the disc brakes and tubeless on the tassajara, but it is the gold series 6061 t6 frame and the hkek has the platinum zr9000 frame but with no disc. the tassajara has manitou axel elite with lock out and the hk has rs pilot sl but i'm not sure if it has lock out? is motion control essentially lock out? Anyway, any insight you guys could offer would be greatly appreciated!!! Any other reccomendations about other brands in the sub 850 category?
