I don't know about changing to the CCS on the Nemsis, but if you're chewing up cables then the problem is the slide itself. Changing the slide would be the answer. I have a CCS on my "Z" and had to shim the front end of it to angle it closer to the string. It pulls the cables too far to the side introducing excess side torque (my opinion). Adding it to your bow, if it can be done, will do a couple other things. It increases the draw length by 1/2" and puts more preload on the limbs (about 5#). Martin's answer to this last thing is to install 1/2" longer cables on bows that accept it.
As far as the A2A is concerned I will refer you to www.archerytalk.com.
The first "sticky" in the Tuning section has a link for tuning bows that is very good. Click on the link and scroll down to post #9 (Nuts&Bolts). He has very detailed info about twisting/untwisitng cables and strings to get a bow in specs.
That being said, I'll be ordering a 2011 Nemisis very soon. I've shot bows with cable slides for decades now and whenever I see the least bit of excessive wear on cables I change the slide or chamfer the edges to reduce said wear. Bear in mind that cable slides, like so many things, are mass producesd and not all will be made smooth as a baby's arse so we have to learn how to recognize what causes problems and remedy them for ourselves. Just changing the cables is doing nothing but throwing good money after bad.
