Another vote for the Grilling Rack. The Summit has more than enough space for me, but I do use the grilling rack as a warming rack. Wish it has some way to lock onto the cooking grate so it doesn't move around..
Same here and I agree with @MichaelM would be nice if you could lock it down. I’d you are okay with only using as an offset the half moon warming rack for the 22” kettle works well and will hook over the handle to keep it more steady.
