I have finished building up my Chinesium carbon hardtail 1X9 and chose to go with a BBC bashwich. I went with the 1/16th inch inner but the clearance to the chainstay is pretty tight, about 2mm. This clearance might be just fine but makes me nervous. I am playing with adding an additional BB spacer to move my driveline out a bit. Running a 9 speed SLX crankset w/Blackspire Veloce 32t w/XTR BB and have used the standard 1 spacer non drive/2 spacer drive side configuration. I added a spacer to the drive side giving me 3 with one on the non drive side. Plenty of room now and drive line looks doable. I just read during a search that you should always have 3 spacers total for these Shimano Hollow techs, should I remove the non drive spacer and just have 3 on the drive side? I didn't want anything mounted on my seat tube so that's why I went the Bashwich route.
