I started at limit and never made it passed 3/6, i have been told this is the level you have to beat, before you really start to make it.
these levels and my under educated play, i lost mostly, i didnt have to intellect to protect my hand.
so on a whim, and bit of tilt i decided i could protect my hand if i was in no limit...so i made the switch

i win more per hour now, and really is just alot more fun for "me" to play.

limit helped my NL game, preflop, reading appointents, reading the board, and most importantly with patience.

i re-tried Limit about two weeks ago, and lost about 80$ in 2/4, so NL made my Limit game worse
But Limit made my NL game good
