Biggest tires for my Focus Mares cx frame w/Stans Grail?

[sowestport]

CX season is almost over for me, and I want to get a set of the biggest tires that will fit.

I have a 2015 Focus Mares CX frame with Stans Grail wheel set.

Any feedback on the big tires (38mm+) that you may have used on this frame.

Thanks guys!

One of the riders on my gravel race ream has run the WTB Nano 40c on the aluminum version of that frame for DK200 and the likes.
