A good weight would be around 0.6 ~ 1
This one is a little special because I also added her chibi style to work along with the regular style. So if you want to use her regular self, use "Sawako". If you want to use her chibi form, use "Chibi Sawako". The chibi from my testing was giving better results with 0.9 to 1 weight but if you want to try lower weights then you are welcome to.
