I recently bought a Weber 18" Kettle and my first try was a marinated Ribeye.
After three grilling sessions (4 minutes, 2 minutes, and 2 minutes), it was still too rubbery and hard to cut and chew, but I managed to eat half of it.
Next, I tried a T-Bone, with no marinade or seasoning, at 4 minutes and 2 minutes. It was great on the Filet and the Strip, and it was easy to cut and chew, so being a Happy Cooker, I ate it all!
