I think its been well said, doing the CPL before the IR is not the easy route by any means, the CPL standard is still challenging in its own way.
While doing my CPL and IR training, i saw a lot of people doing the IR first and really struggle to get through, and after generally got a partial on the CPL skills test too, I have found its easier to switch from visual to Instruments than the other way around, and a lot of these students failed to keep there head out of the instrument panel while on test.
In the time i was training i saw one full pass at IR then CPL out of about ten, and they all said they would if had the opportunity do the CPL then the IR. In allmost said it cost them an extra 2-3 k on there IR training
Hope this helps
