Darton makes a heck of a good bow & is kind of a sleeper in the industry. I really don't think that the bow is your problem with tuning. The Ovation is a good bow & most modern bows tend to shoot very well. I don't think you would go wrong with a Darton, they shoot very good!

I tend to blame other things first before I blame a bow for any tuning issues with broadheads. Almost 99.9% of the time soemthing else is the fault.
