(Sorry for the OT mini-speech) I don't really like 0 increment games OTB. Online it's fine and you could argue that time management is part of the game, but on a physical board you end up knocking down pieces and having a lot of arguments about whether moves were legal or not. 5 minutes became popular when digital clocks were rare and expensive, but these days a digital clock that does Fischer increment is like $50. 3 minutes + 2 seconds is about the same length as 5 minutes and much better suited to OTB play IMO.
