I also found a tool hidden in Corel that doesn't automatically show up on any toolbar. It is called Auto-reduce Curve and after selecting desired nodes (either one by one, window or all) you hit this and with surprising results, will substantially reduce nodes w/o ruining the graphic (seems like it leaves all cusp points to maintain direction changes in a graphic). It will sometimes take away too many, but I've found if it does, just undo, then start window selecting areas and doing the auto-reduce. You can find this by going into Tools, Customization, Commands and then to All (show all items) and scroll down until you see it. By default it is not on any menu, so you just have to create a toolbar for it or add it to an existing one.
