HDT breast collision probelm

[Solitarix]

Hi all, 

I use CBBE Body and this bodyslide preset http://www.nexusmods.com/skyrim/mods/31926/?

I follow this guide : http://www.loverslab.com/topic/25484-setup-breast-collision/to set up the collision.

 

After I do all that the breast collision works 100% but my character's & NPC's butt jiggle a crazy amount, specifically the right cheek. This only happens after I set up the collisions like in the 2nd guide. Before I edit the body files with nifskope there is no crazy butt jiggling and everything is normal.

 

So what can I do to reduce the jiggle and what file do I edit, the hdtPhysicsExtensionDefaultbbp.xml or the hdt.xml ( file in 2nd link) & what settings do I change in the HDT JFF progam? 

 

 

*EDIT*

I figured it, after toying and changing the settings multiple times in the JFF program nothing worked so I just deleted NPC L preButt, NPC R preButt, etc. and the crazy spastic jittering went away while keeping the breast collision.
