what other game would help my NL holdem game, i only play NL holdem, but i always see pros playing all diff kinds of games, ohama, 7card, razz, which one would help me?

ummmm....kind of a weird question, but I guess Pot Limit Omaha has the most similarities to NLHE. If you want to get better at NLHE, you should probably play NLHE. Just logically that makes the most sense.

No other game will with your core understanding of NLHE, actually stick with one STYLE of game, so if you want a break from NLHE go to LHE.

Don't mix omaha in until you've got these games down and have read up on omaha, Omaha is a drawing game and there are no case hands to bet out with like in Hold 'Em. You can always tell the players who are Hold'Em players taking there chances at Pot-Limit Omaha by the way they play.

Seriously stick to Hold'Em for a while. Nothing else would really help.

Limit will help you gaim discipline for sure, but if you really want to get better at holdem, play stud. Holdem is a stud variation
