What sized Gomexus knob for bg 4000

I am going to buy a new knob as daiwa (and shimano for that matter) have awful knobs on their larger reels. What size would be a good fit for the bg 4k? 35,38,41,45,47

I feel the 35 would be too small but the 47 too large. Unfortunately I can’t find any pictures or videos comparing all the sizes.

I have a few other Gomexus knobs but in a different style and 27mm
