I don't want to be negative but in all your threads you mention that you are fairly new to poker - and I'm wondering why you are playing 5NL.
Sure, your $150 dollar bankroll does give you 30 100BB buy-ins and many would say that that is acceptable bankroll management, but it's not conservative, and if you're just starting out you may well lose a fair number of buy-ins in the initial learning process.
If you lost your $150, what would you do then?, re-deposit and just carry on? re-deposit and drop down to $1/$2, become disillusioned and unwilling to re-deposit? I would hope not.
Some will no doubt think that I am being a BR nit but I would recommend that you play $1/$2 now. You will then have 75 buy-ins with much more scope for possible downswings, and when you see that you are consistently beating it at that level, you will be able to move up confidently with your improved roll and play at higher levels, and still have a higher number of buy-ins.
I don't really see any downside to this approach, there's no rush, is there?
