I’d go with a 52mm chainline and this chainring: https://www.jensonusa.com/sram-eagle-steel-direct-mount-chainring-34t-3mm-offset?loc=usa&pt_source=googleads&pt_medium=cpc&pt_campaign=&pt_keyword=&gad_source=1&gad_campaignid=23020030719&gbraid=0AAAAAD_vN010lGfopdgY6wRyym8vfCFyv
Steel chainrings are just the best. The Susie isn’t sensitive to chainline because of the long chain stays. 52 will give you max tire clearance.
