Second Black Opening Choices and good resources to learn them

Hi I’m a peak 2106 rapid player on a bit of a losing streak rn lol and a 2137 otb player converted from my league i play in and am looking to add a second opening as black against e4 so I’m harder to prep against and have something a bit more aggressive to play against lower rated players for easier wins while still being solid and has the possibility to become my new main opening i have recently discovered the Kalashnikov Sicilian and was wondering what good resources there are to learn it free or paid  or if there is other openings you guys would recommend I have decided against the dragon and najdorf for amount of theory and the lines I have prepared against them as white netting me incredible results for info on my style i currently play the worm and attack and other Qe2 Rudy Lopez lines along with the modern Yugoslav and English attack against the main Sicilians and my current main black opening is the modern phillidor which i have ran into trouble against the Shirov gambit and want to avoid playing against it at least in my league
