I went over to Planet Golf this morning for a special sale. They aren't usually open on Sunday otherwise.
I didn't buy anything, but I did get to spend about an hour in their simulator with the intention of finding out whether I hit my Mizuno EZ driver, 3 wood and hybrid better than the Taylormade Aeroburner driver, 3 wood and hybrid.
I don't know the special characteristics of the factory installed shafts in both sets, but data suggests the Mizuno shafts are slightly more flexible. The EZ has flexible settings and weight movements while the Aeroburner is glued together at 10.5*, 15* and 22*.
In the end, it turns out I'm much straighter with the Aeroburner clubs at an average loss of only a 2 yards per club. The thing is, I had set the EZ driver at 9.5*U and the 3 wood at 16*. It was really odd how nothing changed when I went to 10.5*U and 15*, thinking it would make everything equal. Just bizarre...
BTW - I left off the weight in the EZ initially. With it out, I apparently enjoy a tiny bit more clubhead speed, just as I thought from playing it that way. Putting it in cost me an average of 7 yards. I'm apparently somewhat below the curve of being strong enough to use it effectively with the weight in it.
