There's a pretty strong tradition of wrapping tape around the blade that I imagine is hard to break. I wonder how much that hurts the supposed benefits.
The taping method is very player specific. For example, I like to tape from about an inch from the toe all the way back to the heel. Others, like just a few wraps near the toe. For me, a hole in the blade would have no aero benefits but for others, it could matter. The other benefits of the hole as they pertain to the blade flex would still be noticed regardless of taping style.
