[warrantofice]

What i would do is:
I play 9 tables of 25nl. If i double up at one table of 25nl then i close a random 25nl tables and add a 50nl table, yadda yadda yadda. I loose my buyin at the 50nl tables i close it and go back to the 25nl table.

You can make some crazy progress when you run hot and you have enough money behind you to keep moving up. If you double up at the 50nl then you open up a 100nl.

Key to this though is that you never play with more then your original bankroll at 1 single table (well give or take 50 dollars)So you should lets say you make it to the 200nl well should should have 800 dollars at other tables/in accout + 200 dollars at the 200nl so if you do loose you not really wrecking your progress to that point or only loosing your initial 25 or 50 dollars.

(sorry if this sounds confusing)
