I never had any problems with my compound needing maintenance other then string wear. I did a cam upgrade on my old Horton after about ten years and that came with new cables. The only thing I think sucks is that with a Compound style you will need a shop or a press for string service. It is a misconception about How powerful a CB is and how far they shoot. I have shot all mine within twenty yards for the most part. But Never intend on going past thirty. CB's are like high school boys on prom night, they come out screaming, but run out of gas real fast!! LOL!!
