upswing

Its nearly two weeks since i finished my exams and im still riding an upswing which is now the largest from cash ive ever had. The graph above shows the last two weeks and i would estimate $800 to $900 profit after bonuses and RB.
As expected I am playing less now exams are over but this month i intend to reach 2000mpps on will hill for a $200 bonus. I am currently dabbling in 100nl but 50nl is still the bread and butter for me partly because there isnt a lot of action on will hill at 100nl and partly because dont have 20 buyins on will hill. for 100nl. I am comming to realise my bank roll management might be too conservative and my definition of bankroll clashes with the general definition of the poker community "bankroll is the total money set aside for poker" which in my case would be all my poker account balances, scarily this would allow me to play 200nl a level it would take me a long time to reach on my system. Ive been thinking on this for a while and am yet undecided on my viewpoint but i will be trying to make 100nl the norm from now on.
My reluctance to move up quickly is easily explained by my last attempt to move to 100nl on full tilt with 17 buyins loosing about $500 very quickly forcing me to move some money to ft not a disaster but i did go back to my 20 buyins to play system. The benafits of this is it is a very disaplined way to play and online cash is a lot about managing money and disapline.
I have acquired a lot of poker educational videos from Guy which i will be watching over the next couple of weeks accelerated poker learning and all that.

Recently the question of what is easier money cash games or sit n goes has interested me a lot and i have found the hardest thing about this question is what levels are equivalent, to get an idea i have defined a bankroll of $200 and off this size i would play 10nl (20 buyins) or $6.5 sitngos (30 buyins). So im assuming 10nl is equal to $6.5 sitngoes. To compare potential profits in each $/hour seems to be the best way. Now i can stock a lot of 10nl hands with relative ease and i consider myself a winning cash game player but i am no sitngo grinder enter 147_star Paul Williams a winning sitngo player. He is the perfect candidate he is a consistent winner who has logged thousands of $6.5 sitngoes. By looking at his stats and talking with him we have concluded that 6 tabling he could run at a conservative $6/hour. So im addition to my normal levels i will be putting some hours into 8 tabling 10nl and using my new software to give me a hourly rate.
