Hey guys.

So, I'm thinking about starting to play HU SnGs and I would love to have some starting points. Of course, I looked into the HU Digest, but with only 2 links and none for SnGs, it wasn't much help.
So, my question is: are there any good books and/or some must-read articles out there? Do you have any other tips for micro HU SnGs?
Also, what would be considered solid BR management? My current roll is $30 which I won by playing freerolls only and the lowest HU SnGs available are 1.80+0.20, which means I have like 15 BIs.

Thanks a lot in advance.
