Once again amazing catch...
Just as I suspected for a long time I believe that we confirmed it (based on a quick beam measurements) that its swirly mold doe to its 1mm thicker beam in the throat area.
Pure Drive Team (non-swirly) has 1 mm thinner throat thus in my experiments in the past it plays softer than swirly.
Cant wait till tomorrow.
Like Bob said top 10 for last 10 yrs with 345gr racket GASP
