SV2 shocks questions

[JustARcFan]

I'm struggeling a bit with these shocks to get them right.
I'm used to Kyosho shocks so lets say that I was a bit spoiled.

Could somebody give me a little help for an astro track (medium/high traction)?

First thing I already changed are the 0 rings as the shocks were already leaking just looking at them.

I have 5x1.3 tapered pistons in the front with 40wt oil and 5x1.4 tapered pistons in the rear with 35wt.

Is there some magic involved like cutting the bladders or...?

Looking forward for some input.

Cheers!
