Current largest glass pads? Recommendations?

I'm looking to buy a large glass pad. I think these are the largest?:

1. Pulsar Superglide V1 XXL: 980 x 420mm
2. GLSSWRKS Polarity: 560 x 480mm
3. Cerapad KIN X: 605 x 405mm or 505 x 505mm

Any really large ones that I am missing that perhaps are not sold out everywhere? I have the Superglide v2 and I do not like the surface, the microbumps were too large so it always felt scratchy to me. So I don't think I would like the v1 very much either.

I am currently running the Pulsar Pro MEIY 500 x 450mm and the surface is basically perfect for me. It's smooth and feels great, while not being nearly as sticky as the v2, but I don't like the artwork much and I was hoping to get something a little larger. I like a balanced to fast pad with minimal noise/scratchiness.

I'm leaning towards GLSSWRKS Polarity, but I thought I'd check here first. Any help is appreciated!
