Do you know that it's the same ferrite mix? That makes a huge 
difference, and #31 the only one I've found that yields REPEATABLY good 
high Rs values at HF. #43 and #52, which can provide high enough values, 
but they are much higher Q than #31, so the wide mfg tolerances of all 
ferrite cores causes every one to be different.
