The crossbow industry went crazy a few years ago. Some of the bows hitting the market have so many bugs . Companies are in a space race for speed, rushing to get new products onto the market, basically pushing prototypes onto customers and using them as beta testers.Models can be discontinued after just a couple of years for the next seasons even faster bow.
This is an old thread and not sure what the OP eventually did. But for anyone considering crossbows my advice is
1. Dont chase the latest and fastest bow on the market. Unlike compound vertical bows which are usually solid, tested products, new crossbows can be far more 'prototypal and experimental'
2. Choose a bow that has been on the market at least 3 years. It means the company has accepted the speed , the customers are happy with both the speed and quality. and any bugs should have been ironed out.
You can go as fast and as fancy as you want of course, just be prepared to tune, tinker or ride the warranty carousel as required.I remember one of the worlds fastest brands putting out 450fps+ bows a few years ago and it was having such severe issues the DIY 'fix' circulating on crossbow forums was to take a hair-dryer and heat up and reshape certain parts of it. Melting and reshaping parts of a factory product worth over $1000....good heavens..
Excalibur used to and probably still does the best, toughest, most accurate recurves in the world. I have owned two of their products. Even they got the speed bug and cycle through models a lot fastee than they used to though.
