Hi, Chosen feds are AEW, WWE & New Japan because they're the biggest feds and variety is the spice of life (also not everybody watches WWE weekly either...).
There's no penalty for skipping a show, and also given how wrestling works there's no guarantee that you'll get everything right just because you watch every week either... If I had more time I'd probably include NWA and MLW too (and, tbh, if NWA get to regular programming and PPVs again they might get in anyway depending on the timing).
Enjoy the ride - you might be tempted to watch something you otherwise wouldn't and find some fun stuff
