I can't wait to move up deal with a little tougher competition because it will be more mentally stimulating.

You might want to consider cash games. What (theoretically) makes no-limit difficult is the prospect of being faced with very large bets on later streets. This doesn't happen in tournaments (except in the early rounds of very large live tournaments) because the blinds are so large in proportion to the stacks. Play a 200x BB cash game if you want a mental challenge, and stay in after you've doubled a couple of times. When you and your opponent each have 800+ BB in front of you, "mentally stimulating" doesn't begin to describe it!
