I know there are threads about bankroll management, but I had a question about my specific situation.

To re-cap first.... There are a few guidelines I've seen out there for Holdem BRs:

1. Go up a level when your BR reaches 500x BB, and go down if you drop below 300x BB. (This is by far the most common suggestion.)
2. Don't go up unless you've won at least 100BB at that limit.
3. Play for at least 100 hrs (total hrs, meaning multitabling counts cumulatively towards your hrs) at your level before moving up.
4. Your BB/100 should be at least +3 or better.
5. All of the above.

So here's my situation: I came into about $1,500 out of nowhere lately and decided not to buy some new electronic gadgets or something stupid, but to invest it in this new, fun hobby of mine... well at least for now, until I see how things turn out.

I am fairly new to poker (only playing recreationally w/ friends) and have been playing online for a while at mostly at micro limits. I've been winning pretty consistently (def over 3BB/100), since I originally started at the lowest .02-04 limit, and I've been very slow & cautious about at moving up in the micros.

According to suggestion #1 above (the one I've seen most often) I could in theory afford to play $2-$4 right now, but I truly don't think I'm ready for that level and would likely get beaten up. I don't want to see my bankroll disappear quickly, so I'd rather be ultra-cautious and start from the ground up -- without have to necessarily grind it out for what will feel like 100 years.

So my questions is, for someone like me who has a bankroll which probably far exceeds the stakes I'm skilled enough to play at this point, what guidelines should I follow? And if/when I reach the point where I'm playing within that 300 to 500x BB level, how should I proceed from there? Are suggestions #2-4 (above) worth obeying instead? Or perhaps in conjunction with #1 as well? Thanks.
