Hwong,
I'm quite expressed of your beautiful Sanke, she has not a lot of sumi, that's I like the most in a Sanke. I don't like the big patches of sumi on a Sanke you see nowadays..
Your Sanke reminds me a lot of a Sanke we bought 2 weeks ago. Altough your Sanke has a better hi patch on the head a think. Our Sanke is purchassed by my dealer as a Jumbo tosai from 40 cm on the auction of SFF last year. She was then 10 months old. She is a daughter from Akizakura and a male from Wakashoryu. She is now 61 cm and I hope she will reach this summer 65 cm. We don't have the temperatures you have

in Holland. She is now in our pond at a water from 20 degreeC. We warm our pond.
We bought her for her nice musculear body, very very white shiroj and very little sumi spots. Maybe she gets in the future more, I hope not too much!!
You see a little picture from her in my avator, but that photo does not do her right. I will later posted some better photos from her.
A lot of luck with your very beautiful Sanke, she is really my type of Sanke
greets,
Fukarin
