I have a 22 that I purchased new before Weber came out with the grommet so I cut a small slot in the lid to accommodate my Maverick wires. I recently purchased a 14 that has the grommet and can say, with confidence, that I don't like it and will slot the lid. Problem as I see it is, if you want the probes (meat and Bbq temp) on top, you need to thread them up through the top grate. Then, if you want to do something on the bottom grate, i.e. check meat temps the probe cables just get in the way and complicate things. Just my 2 cents.
