It depends on how relevant they want coil1 to be. If they still want it to be relevant then it'll be ilevel 90 same as Coil1. If they don't mind it'll be 95. CT is basically your PUG raid. They don't intend for you (yet?) to have 24 man raids so CT will be a PUG raid and will be tuned as this. Coil2 will be you're serious FC raid.
