Interesting that you are pursuing both at the same time. Why? That presents much more risk to you, in my humble opinion. I was grateful that I had already been a seasoned CFI for awhile before persuing the CFII. Not sure why you feel you need to unless you think you might save a couple of bucks banging them both out simultaneously; especially when the vast majority of your instruction will not be instrument instruction. I think the expectation for excellence from the POI will be held at an even higher standard then.......
