Here is a link to a guy on AT that has a Slayer for sale with Nitrous X "B" cams on it. Last I looked he was down to 310.00 for the bow with sight and stab. If I wasn't so broke it would be on its way here.
The pics he has posted shows the system real well. http://www.archerytalk.com/vb/showthread.php?t=1418964
What a beautiful bow and a great offer. I would take it if i'd had the money..
