OK, first of all, you say that the bow works well and shoots well. That says a lot. I have not owned a Stiker model, but have had 3 other bows on that riser. I have had a Darton Viper for quite a few years. I keep it around for a backup because I really can't sell it for much money anyway. This bow has outshot (in my hands) more modern bows by Mathews, Hoyt, McPherson, and High Country. I still have the Viper, and the others are gone. This summer, I shot within 1 point of my best score ever with the old Viper. I guess what I am trying to say is that the way a bow shoots for you is the most important thing, and if your Striker is shooting well for you, why get rid of it. I would at least hang on to it until you are sure you have something you like better.
As far as Darton bows in general, I have 3 right now, so I guess I'm partial. My Darton Tundra is as good a bow as I've ever shot, and better than almost any other bow in my hands at least.
