John, I would have used SORT-COPY (but if it's DFSORT make sure the VSAM BUFND setting is optimal). It should be faster than IDCAMS (because of the better TAPE I/O).
Are you sure you need to reorg at all? I'm sure you are familiar with the "cost of CA splits is mainly at split time", etc., and re-org potentially causing more CA splits if it reverses needed splits .. How did CA-FAVER solve this problem? In-place reorg?
