John You can still use leading wildcards even if you dont have the ReversedWildcardFilterFactory in your analysis but it means you will be scanning the entire dictionary when the search is run which can be a performance issue. If you do use ReversedWildcardFilterFactory you wont have that performance issue but you will increase the overall size of your index. Its a tradeoff.
When I looked into it for a site I built I decided that the tradeoff was not worth it (after benchmarking) given how few leading wildcards searches it was getting.
