125 is in the "elite" spectrum of club head speed. I honestly can't tell how fast your swing is from that recent video you posted, but I do recall seeing Tiger Woods, DJ and Bubba Watson in a tournament about 1.5-2 months ago. They all teed off on a par 5 on the back 9 and their swing speeds were all in the range of 124-127 (if I remember correctly). Obviously they could swing faster if they weren't trying to hit controlled shots in the fairway, but it was still incredibly fast to my naked eye. So when guys hear a swing speed that high, they will naturally be skeptical.
I wouldn't say 'elite' spectrum per se... Maybe on tour - guys that can actually play. But 140 to 150mph is 'elite'. That would be the long drive guys. Not the tour professionals.
