Tom, I'm guessing that if your grate rails run from left to right, parallel to the front of your grill, you might have a bit of a problem with sliding a spatula under the food from the front side of the grill - it might not go under the food smoothly, especially fish, and it might bump up against the next rail. Maybe someone who already has them could check that for you.

One more question... My grill has sideways-oriented burners. Wouldn't having the GG run sideways be better for me than the front/back setup I see in most of the picks? I'm thinking one 5" GG longways over the front and back burners. That leaves a 7" section in the middle for indirect since my grilling area is 24" wide x ~17" deep
That means paying a bit more...
Am I over-thinking this?
