You ask if anyone has done testing/demos. Well, obviously you have. But how
about simulations? They can also make the same point you do. In fact, for
many mid-to-high handicap golfers, the higher loft is not only more accurate
but longer as well.
A few years ago Golf Digest did a test and determined that the ideal loft for a 85 mph swing was 13 degrees. Of course this was before the advent of large clubheads and Titanium.
