In my mind, the reavers in this list don't work. Because even with skilled rider and a 3+ jink you kill one and they are making a LD test on an 8. I played a small game this past weekend and joined two eldar characters on bikes to a 3 man squad. 2 bikes were killed, they failed leadership and the unit ran off the board. That said, I like reavers. I just think you have to have bigger squads.
