I have used the epic regularly for two years, with moderate success overhand. It does however take awhile to learn how to place and control it. In a slight headwind it will add significant distance, not to mention it fun watch and throw. I am a firm believer in it and will always carry one in my bag.
I have yet to find any other use for it on the course as stated above.
the strength of your arm and throwing ability (baseball) plays a huge roll.
