Trying to decide between the Super Walk Behind 54 inch or the Hydro Walk Behind 54 inch. Is the Super worth the extra $500? Any pros/cons of either. I currently own a Hydro Walk behind 37 inch so I am familiar with Hustler. I would not be using a grass catcher. It seems as though the Super is has more power than I may ever need, but maybe that is a good thing. Any advice would be appreciated.
