Tbf violent momentum actually does a lot more now than it used to when this debate was originally started. And those same builds rarely included go to skills like synchro and donnybrook. It’s just not super optimal was all i was bringing up. Personally I like to play CCC with distributed denial and stop gap. Or big boom blaster. If you don’t want to go all the way to capstone, I think sitorak is a really solid choice. Even still bbb tbh.
Also, i would like to point out, that with Seein Dead, my kill skills are always up
This mod may also shine more once level cap is increased. From there you can actually get the damage reductions, damage, life steal, and speed that is needed all at once.
Seein Dead is the closest com to mimicking a level cap because technically it replaces a capstone and enhances it.
tbh when I first replied to this topic I didn’t realize they were playing ccc with rr infiltrator. I thought it was just infiltrator in general.
The infiltrator works very well with Brawler. Particularly I use it with Nova berner + Distributed Denial clone. Can be replaced by frozen heart for cryo builds. I haven’t tested it yet on M4, but M3 works very well. Kills almost anything.
I have a few brawlers, no anointed cyro ones, but i may give it a try, i typically use the Transformer with 15% movement speed or the re-Router for damage
Want to play hardmode infiltrator? Equip a deathless. 
The nova berner is a shield that synergizes very well with distributed denial. It generates novas fires when discharged and fully charged. mod infiltrator + nova berner + Clone + distributed denial = 5 novas 25k. This combo works great on M3, I need to test on M4.
I’m waiting for Krieg’s DLC to return Flame of the Firehawk, leaving the OP infiltrator. It doesn’t hurt to dream …
I have never used it, not even sure i have a Nova Burner, will have to check it out
