I'm not very familiar with the babolat or yonex racquets that you mentioned. I've been fearful of babolat since I have a glass elbow. However I did hit with the apdgt 2013 briefly and I don't think the speed is as stiff as the babolat. It's stiffer feeling than the current speed though. It's less than the extreme pro 2.0 which I've been hitting lately, so somewhere between 62 and 69, maybe 65? Just a guess though.
