Hoyt Vortec, HavocTec, and I have a CyberTec on the way. I have always just put my rests on the bow, without the adaptor plates. You don't REALLY need them, but they are nice. I think when I set up my CyberTec, I will use one of the Hoyt plates. The only reason I would like to use one, is because it would allow me to take the rest off, and put it back on without having to re-tune the rest.
