Either option should be fine. Just remember that if you go with the 23* and bend it weak to 25*, you will reduce offset and add bounce, but 2 deg shouldn’t be a problem.
I have a set of Tour MB’s. I play the 4 iron, but I have an AF-903 23* that I have bent to 21.5* and it works a treat.
Good luck.
PS: are you playing the latest version of the MBs? I have struggled to find any meaningful reviews of them and would be keen to hear what you think.
