"But they have lots of limb issues."
You cite three examples, without going into details about their occurrence, and make a generalization about the brand. I'd had a Parker blow up...but it was my fault. Parker fixed it anyway, no questions asked. I'd want to know HOW the bows malfunctioned. Had they been fired with too light an arrow? (same as partial dryfire). Had the limbs been abused in any way? Was a faulty string involved? (If the serving wears through and into the string strands - even one or tow strands - it wakens the string). Had the bow been pressed properly? Did the arrows have moon nocks? Etc. Etc. Etc. The most common cause for bows malfunctioning is a loose NUT....the one behind the trigger!!
