Sadly I didn't hear anything about the older frames. Is it the MK1 or MK2? Haven't seen anyone with a DC on a MK1 Capra. But doesn't mean it doesn't work. A lot of people put DCs on their Trailbikes because of the nice steering stiffness. But a frame eon't crack with a DC just from normal trail riding. Mostly bigger jumps, hits and drops force the frame to crack. The only thing I heard in terms of frame Problems was the early versions of the MK2 Capras chainstay that cracked on a drain port.
