I dunno.... Based on Tom A's testing I think the SS 23mm might have the aero to overcome the 20mm poor Crr, especially after what James Haycraft found
Still, a 20mm SS will be more aero (particularly at high yaw) so it's a tradeoff between that and Crr and potholes. I used SS20 on this rim last year.

My front rim is <17mm internal and 26mm at the tracks, so a SS23 is only ~23.5mm wide. I would stay below the width of the brake tracks on the front, if possible.
