For one you have warranty !and you get the most up to date modifications and changes . If you decide to trade in the following season you'll get a better buck for it . I think the new bow's have come a long way when it comes to drawing smoothness and vibration's compared to previous years .I know your bow is a good one and to upgrade I agree is it worth the extra $$$$$ and your bow to upgrade, maybe not ! But that's your choice .I feel if you don't upgrade at least every other year you might as well hang on to your bow because you won't get what you feel is fair value .But definetly new gear isn't all that different to justify the amount of $$$ you have to put out to update .
