Dave, CSS are by far the most accurate, maintance free, and shooter friendly bows you'll ever shoot. If you want to shoot competive 3D though, I would consider the System rather than the Challenger. Of course, this is just my opinion. Mr. Nease and company have done their homework and it certainly shows in their bows. Give him a call and see what he can do for you. Hope I've helped some. Take care and have a great work week.

In Christ,
