I know that some hobbyists see K-Girls exclusively and that's perfectly understandable. In the last year I have been at about 70% K-Girls with 30% other ethnicities, mainly Caucasian.
Some years have been higher, some lower but I don't believe that I have ever dipped below the 50% level.

I used to mix it up in my pre-TER days, but I prefer thin pretty brunettes, and in THAT category for me now, there is only one choice. If ALL providers charged the same, and the service was across the board similar, I'd probably go back to rotating between all of the available flavors, but right now the K flavor is a great deal on a great product so I order the same thing every time.

A couple years ago, I would have said 50/50. Now it's more like 80/20 in the k-girls' favor. They are highly addictive, that's for sure.

I like all women but my best experiences have been with K-Girls.

30% k-gals, 70% others

I see almost exclusively Asian girls.  95% K, 3% C, 2% T.
