Depends on your timescales really - someone told me the other day that the IR syllabus is due for a shredding.
So why bother with the ATPL if a CPL will fit the bill in the near future? Then due the new IR thing when/if it comes out.
It all depends on what you're after the licence for.
Health Warning: It was someone at a training establishment that told me about the IR shred but they had nothing to gain out of turning me to the CPL rather than the ATPLs. The CPLs suit me.
