Hoping any of you Weber Q owners could chime in on this. Would using GrillGrates on top of the original CI grates affect the performance of the Q or would it be best to just stick with the CI grate by itself. I'm asking because i just recently purchased GrillGrates for my beater Charbroil and would like to still utilize them, but don't want to degrade the performance of the grill. So if anyone has tried using them i would like some feedback
