Slipper question

[Welshy40]

Guys, I am a bit puzzled about slipper settings for these twin pad systems. I unsure how you guys set yours for high grip such as astro or carpet for 4wd. Some cars sound like they slip quite a bit at the start and some dont so basically need a simple setting so I get some slip to aviod ruining the gearbox from standstill yet traction and fractonal slip during the race. All advice is muchly appreciated. Thanks.
