Continuing a bit with the thread drift, I think there is way too much emphasis on scenario training now and not enough emphasis on how to fly the airplane well. Quite honestly, that's one of the better reasons for getting the commercial--the learning and practice and perfection of stick and rudder stuff, so that instead of it being difficult, it becomes second nature. I think instrument students are also often handicapped because they don't yet know how to fly the airplane well, which again should be second nature so that throwing in instrument procedures isn't information overload. I also advocate taking aerobatic training, not to become another Sean Tucker or Patty Wagstaff, but to become a better pilot.
I also agree that memorizing the "book answers" shouldn't be allowed. That's learning to the test, not learning the material for real.
I had my commercial before I started my instrument training, too. It was mandated by the VA, which paid for 90% of my advanced ratings and licenses (not certificates back then). I guess their reasoning was that if the instrument came first, people might stop there, but if they were ostensibly working toward a vocation, the commercial was the way to start. I did single engine charter VFR only, but I already had my instrument rating by then.
One of the mistakes that was prevalent then and still is a mistake is that CFIIs don't need to have ever experienced actual IMC to teach instruments. There is such a difference between flying in the soup and flying with a hood on.
Looking at the Commercial PTS, though, I don't see that it requires all that much different from what we had to do to get the commercial way back when. Both the private and commercial PTSs have been updated, effective June 1st. I notice that the stall awareness section differs from the private PTS, in that in the private, a stall is to be recovered from a "fully developed" stall, whereas the commercial requires recovery at the "onset (buffeting)" of a stall. Both private and commercial PTS now require demonstrating an emergency descent. Otherwise, it seems to me that the PTS simply lists all of the things we had to know then, but then we didn't have the luxury of a PTS to guide us (or the examiner). I would think that would make it easier now, to know what you need to know.
I also think the advice I was given way back when still holds true: take the ride in the simplest airplane with the simplest avionics which still comply with the requirements. Back then we didn't need a complex airplane; now it's required. But there are complex and there are complex--go for the simplest complex (some oxymoron, right?). And make sure that you know how to work everything in the airplane!
