Race day shoe similar to Superblast 2 for marathon?

Hi all, recently I've been having issues with shoes on the softer side (EVO SL, Neo Vista) especially on longer runs since I end up sinking in them and it really flares up my PF. The only shoe this doesn't happen in is the Superblast 2. I love that it's fairly firm and on runs for 30+km feel the exact same as as when I started, but ideally I'd like something a bit more aggressive, and light for a marathon PB. I've been using the Hoka Mach X2 as a firmer shoe for speed workouts and those seem to be alright, but I've never taken them out for anything longer than 15km.

Any suggestions? Based on my affinity to the Mach X2 I was thinking of the Cielo X1 2.0, but I don't know if it's wildly different to the Mach X2. I unfortunately don't have a lot of running stores near me so I can't try them out in person. I have my marathon May 4th, and am aiming for 3h15m. I'm 5'10" 170lbs, if that matters.

Thanks!
