Jim -

Add me to the list, I've had cores disintegrate over the years.  I use several them at the base of my 80 and 160 4-square verticals, wrapped in electrical tape to hold them together.   The problem could have been freeze/thaw cycles, or heating when one of the verticals detunes when it breaks and I didn't notice the problem on the shack end.

I suspect those of us in ice/snow country see it more often than the San Jose area does...   Haven't found a good solution yet, I have trouble imaging that the addition of a box and associated connectors, caulking and hardware will be more reliable over time.
