I played with 19-20 mm constant beam racquets all my life, but recently I experimented with some old Prince Shark MP, which has 26-22 mm "aerodynamic" frame. I modified it quite a bit, and it turned out headlight and polarized. What I found was much better stability through the contact compared to classic designs, and now I'm wondering what could be the reason. The racquet has ample swing weight and twist weight, thanks to those massive "shoulders". Clearly the tapered/aerodynamic frame really helps to fight twisting. But the most important thing is, such design forces me to hit a bit more through the ball, so that I don't frame it. I can still put a lot of action on the ball, but now I'm more cautious and calm (and relaxed too!) in how I brush it, which is exactly what I need to put more pressure on the ball. For everyone who thinks that wide beam can "get in the way" of how one can work the ball, this "obstacle" can be very beneficial as it will force some very good habits (such as hitting more through the ball). Now I can see how AeroPro/Pure Drive designs won such popularity as "tennis made easy" technologies.
