What is the right line and length ?

[Sooda]

Hearing alot about this but I'm not as big of an expert as others here ...

 

So, what exactly is the correct line and length to bowl in South Africa , sounds like it is "just short of a good length" and maybe just outside offstump ? ; is that right and  is it the same as in other overseas conditions?

 

Sounds like Shami and Jasprit were poor with theirs yesterday, and Pandya bit mixed

 

What is the right line and length to bowl at home? Would it be On the stumps and fuller?

 

And why does it need to be so different in different conditions (swing and bounce in guessing)

6-7 meter is the right length, just around 4th-5th stump.

[Pollack]

Line: 4th/5th stump

Length: a bit short of good length

with occasional mixing up of both line and length like firing some into the batsman and occasional outswing from 4th stump.
