First things first...take pics of your cable routing on the cams so you can reference them for your first time. Make note of which cable goes through which roller on the cable guard, and which cable is on top of the other. Take measurements of your current specs, ATA, BH, peep to center of nock point, speed nocks from edge of cams, take pics of the prelean the cams have if you want. You're going to have to retune from scratch, but it'll help if you at least have an idea.
Once you get everything installed, I'll go through my steps on what to do, and when to do. Its important not to do some steps before others, like tie on your loop right away to try and set nock height. There's reasons to wait. But get 'em on and get going. Good luck.
Reading my last post, it probably sounds like I'm splitting hairs, and maybe I am, but I've heard that the placement of the speed nocks with the Z5 cams is pretty crucial to the bow tuning properly. I figure it's better to ask now rather than later.
