re: Poker & If you have to follow one of these players....
If you're looking to expand your poker knowledge base, my suggestion is to watch as many different people on Twitch as you can. Watch them for an hour or two, see what they specialize in (cash games, MTT's, etc.) and see what person(s) works best for you. The two you suggested are really good streamers, though I haven't watched much of Mike Gano up to this point.
Felix Schneiders (xflixx on PokerStars
) is a good streamer as well, and is interactive on Twitter. He's endorsing the current Cardhunt promotion on PokerStars, which I have been taking part in as well, and it's a really good promotion.
