*.ucas *.utoc *.pak > xtunreal+srep:m3f:a2+dispack070+lolz:d128m:mt4:mtt1:lmdf1 > 1.87gb = 1.19gb

Thanks to @wrathma for providing the oodle library for XTool.

you might have used the wrong oodle library. try the one i attached. here are my compression results -

*.ucas *.utoc *.pak -> xt_unreal+msc:raw+srep+lolz
1.70gb => 1.10gb

everything else -> dispack070+delta+rzs
393mb => 119mb


overall size 2.08gb
compressed size 1.21

edit: xt_unreal is xtool -mkraken+mermaid, you dont need unreal.dll and you can skip msc:raw it gives about 50mb difference.
