Dave,

For several years I have followed and listened very closely to things you've said, seen, and done. I pay attention to your insight and experiences. You've got you're finger on the pulse quite decently- but you have not seen everything. And there's no arguing MDS can fail and frag a hemi. It happens, it happened numerous times, it will continue to happen. Dont believe me or the OP? Just Google it. You already know I've had the failure. I'd bet there's more on this board who have suffered it as well and nary a peep from it. Please stop saying it does not exist.
