It would be helpful to know WHAT MADE THEM EXPLODE. Such issues as using improper nock, nock not oriented correctly, using arrow that is too light, sting that is frayed, arrow not inserted all the way back to string, etc all can cause a bow to "explode" but they are not the fault of the bow.
It would also be interesting to know what Parker did about it.
Ultimately, compound bows-not unlike trophy wives-take special care to keep performing. Want a no nonsense toughest bow hands down? Get a recurve, EXCALIBUR to be exact.
