Oddly, it is the BHBR that is notching. I think it is because the mains are freer to move now. I might be hitting harder, too, as the ball's flight path just arches down so quickly. Keeps it in, but I have noticed more short balls. Not all the time nor are they that troubling (they land just inside the service line and peak near the baseline), but they are there. Just wondering about other's experiences. I may have to try syn gut at some point, but I kind of like that extra crispness of the poly.
