The stream thing was pretty new for me, too. Generally, I still don't get it... I understand the founders, the site owners and generally why the establishment are pushing it, but I do not understand the 1000s and more all the time followers - it is not only about the poker, generally all kind of 'strange' streams, streamers...
I watched several times ACR streamers, I liked TheBoski and killingbird streams. They are not the best players on the world, but pretty good to watch them, they have some character, play low MTTs, too, what I do.
Especially watching Boski wasn't so good for me, and generally that is my problem with streams, most of the players have a bit different 'strategy', range, it is generally does not fit to me, even I understand, they reach FT more often, probably the ROI is higher and the ITM is lower than mine, but the
bankroll what they need for it, is much higher what I can afford without afraid to lose.
However, who likes MTTs, I can recommend both, especially Boski, he plays almost every day, reaching FTs quiet often, so you can see the way how he reaches it. Few times it is simply good for fun, even if you do not learn much, apply to your own game play.
