the toothless disc will help keep your trouser leg out of thje chain.
* may lack the Shift pins and ramps , but Surly Stainless steel ones are Long Wearing.
then you have the 26~28t for hills. 16t drop to 3rd ring seems to work good.
My FD was going between 42 and 52. I know the 10 tooth spec. It sure likes to go between 42 and 45 smoothly. I guess I could look around for a front plate closer to the 45t size but where its pushing on the chain is way back and it doesn’t know it only has to jump 3 tooth jump.
