Got a DC membership so as to improve my game as I have hit a rut and cannot beat 50NL@Pokerstars

Got started looking at videos which showcases the stakes I currently play at and noticed that the 50NL videos from a couple of years back are in no way reflective of the standard of play at 50NL currently. Seems that 50NL at FT a couple of years back is really soft.

So for good videos, should I be looking at the 100,200NL vids instead?

or its a totally different game?

Yeah, you probably want to look at the higher stakes games. I was amazed when I watched some of the old 25 and 50NL vids a while ago. Some of the fishy play was as bad as I see at 2NL.
You can learn something from just about every video on DC, though.

Watch anything with jk3a and wiltontilt combo.

WiltonTilt is awesome.
