I have a 2002 Gibson L.P. standard with an A-Bomb in the bridge. Drop C# tuning medium top heavy bottom. Strings. Sounds awesome through my ReVv Generator 120. Tight and ballsy with lots of snarl.
Was thinking about A-Bomb, but i'm closer to juggernaut or something similar?
cause my band's style has some quick like "system of a down" parts like the
first song from this album!

That's my band's latest release by the way! 
Why are you thinking the Juggernaut?
I have a Juggernaut set in a 6 string superstrat with a locking trem and in a 7 string hardtail superstrat.
I'd say that the juggernauts are quite low mid focused in tone but they are super versatile excelling at cleans, leads, and low / high gain rhythm. I use an ibanez style wiring with a 5 way blade switch for both of them. **NOTE** both these guitars are very acoustically bright instruments with not a lot of low end.
The A-Bomb in the Les Paul will definitely be closer to your band's sound. It has more hair & snarl to the sound and it really excels at blues and crunch / rhythm tones. It does solos and leads fine with the right amp but it's not a jack of all trades like a Juggernaut is. My only real concern with a Juggernaut in a Les Paul is the predominance of low mids but one forum member here really liked a Juggernaut in a Les Paul. It comes down to preference.
The Rebel Yell N / A-Bomb bridge combo is amazing in my Les Paul with 11 - 52 strings in Drop C#. I think it'd work REALLY well for your sort of style!
Thanks for listening our stuff!!

Well i have an Suhr Aldrich on the bridge and lately had some cool results having it
way down from the strings, something like 4 to 4.5mm!!
I really liked how compressed on the lows the Aldrich is, but i really hate
the way it pronounce everything above 1.0 Kh, so having it that low
and lowering the treble side poles as well gave me something closer
to what had in mind first place!
In that direction i wanted something more modern than my Aldrich fellow,
in order to make the whole LP more modern!
Ben suggested Aftermath Bridge and Cold Sweat Neck,
but your thoughs here about the AM made me skeptical and although i know
Juggernauts are not made for LP it seems that they are
the "one step back"(versatile & compression wise)
from AM pickup on Bare knucle roster..
Which LP friendly pickup do you think that would be near as compressed as AM but a little
less sterile?
