Lots wrong with the old tear drop steel cables!!! They will rust and break at the tear drop, which happened to me several times on the 70's and 80's bows that I owned. Of course it would have helped if I wasn't shooting 80 pounds most of that time also. I also had lots of limb problems back then too. Today's bows are better constructed and engineered to last a very long time and regardless of the cam system, will shoot better than you can hold it. Most of today's cam systems are marketed to sell bows, plain and simple. The cam system is the the item that will make or break sales for most bow companies IMO. Good luck with your's
