I don't do any of mine. First, they all have fairly thin manes to start with, second I don't show, third, they only wear halters when I'm working with them.
They do all have relatively short pulled manes, so it's just not a big deal to part the mane and pull the forelock foreward.
In general I would say not to do a bridle path unless you can maintain it, nothing looks worse than the inch tall mohawk at the bridle path.
I can see that if your horse had a thick mane or if the mane was worn long, it might be better to maintain a bridle path, but for me it's just not worth it.
