Japanese, Kana to romaji. What do you prefer?

So many different ways, it would be nice if there was an official way, romaji is such fail

1を
A)o or B)wo
2ー from katakana
A)- B)nothing C)double vowel

Now I know for things like し and しょ are usually written as shi and sho, but is it just me or am I seeing of si and syo pop up more often than it usually does? Maybe it's from more professional things though, e.g. mainichi issyo ps3 download game

The western world has basically settled on Halpbern (I think that was the name, I don't really give a shit anyway), whilst the Japanese use other systems (I don't remember the names).

For example, we romanize "し" as "shi", and "ず" as "zu", whilst most Japanese romanize them as "si" and "dzu".

Using the western system, it would be 1B, wo, and 2C, double vowel. Hope this helps, but why are you even giving a shit about this? Anyone that's studied Japanese for two weeks should be able to understand both.
