There is nothing wrong with using the Tree API, except that it doesn't perform as well as the flat API.  Now don't let this scare you off - in terms of performance, we're talking 5 ~ 10% and if the API works better for you, then use it.  But you should benchmark for yourself and see whether you need to extract this extra performance in exchange for reworking your data model.  YMMV.  :-)
