I've been reading theory, grinding my ML points, 
and now I want to Get Organized and Serve the People. 
I know this is largely a regional choice, but among the major Marxist-Leninist orgs, which are doing the best work, in your opinion? Not asking anyone to dox what org they are in!
I've seen FRSO and 
, but wanted to know people's general opinions on them, or other orgs I should check out. I have a firm belief that proper theory and practice leads to better results, so it's important that theory and practice are both good. Additionally, the international struggle must be paramount, since this is 
Thanks! 
Witness Cowbee's attempt at building Communism in 2024! 
In terms of proper theory/practice I have some bad news and perhaps a suggestion for you. Unfortunately both revisionism and a broad anti-intellectual attituide are hegemonic today. From my experience theory, if it is even studied at all, is done in an ecltic, unfocused manner based purely off of personal interest rather than directed at understanding / strategizing about a particular problem--theory and practice are entirely separated.
PSL kind of indirectly enforces this by overemphasizing capital P Party (actually Procedural really) discipline among its members. With every comcievable task officially delegated, for instance, if there's an event a such-and-such person will be told they are responsible for bringing water, the other fliers, etc. Such explicit, granular control is fitting more of a boot-camp than a Communist Party in the sense that there is no way creative applications, or avant-garde developments can occur in such an environment. Not to mention the problem of dissent & censorship endemic among Trotskyite groups.
I'm being too detailed for what I want to get across in this comment. Although I don't necessarily agree with them 100% the Unity Prospectus by USU covers the lay of the land of the US left quite well:

I guess the advice I have for you is that while you should get involved in whatever is available, you should do so with a critical eye--never lose persoective on the ultimate goal of a Communist revolution; understand the difference between tactics-as-plan and tactics-as-process & don't get lost in the weeds. With that in mind, always strive to criticize incorrect ideas, no matter how unwelcome it may be; claim no false-unity either, divide what can be divided into two sides. Have a sense of separation and think of it as an investigation.
