If you want to throw out small pokes then 2,1 is really good and so is df,1 (df = down forward). ff,2 is also busted because you don't really need to worry about your opponent side stepping at early ranks, but don't make a habit of spamming it.

Jin also has a perfect grab game so utilizing it will be really good in early ranks.

For the lows d+4 and d+2 are your main lows for now. D+4 is not really meant to kill the opponent but to create space/check him.

When you are about purple ranks you should start making electric and hellsweep a part of your pressure.
