After doing this mod for several years, I settled on enlarging just one of the three pilot bypass holes (the middle one) and set the mixture screws to 4 turns out.

You also shorten the springs 12mm instead of 19mm, right?

Yes. 


As the bikes I was working on got older, I found that the springs became slightly shorter after years under compression.  If you cut the spring too short, it starts to lose control over the slide. 


Cutting it to 12mm also allowed a bit more excess to bend over to the horizontal, which prevents the spring end snagging in the carb top cap.
