RE: Changing Hoyt Trykon Cams with Vectrix or Katera Cams??
The price probably won't justify it.Hoyt charges an arm and a leg for new cams,even if they will work,which I suspect they will but a call to Hoyt will get you the info you need from that standpoint.
You will need cams,strings and cables.Not sure what that will do to the poundage on your bow but itshouldn't change it.
You are probably looking at $200 for that swap,maybe more after all is said and done.
