Picked up the Radspeed driver yesterday at a an area pro shop. I have already cut the shaft and changed out the grip. Dialed in the swing weight nicely for me. Hit it on my launch monitor about 10 times and seems nice.
Not sure how much difference I will see with my Cobra Speedzone versus this one, but thought I would upgrade anyway. I have four different shafts that fit so this will be fun to see which one dials in the best.
My guess is I will stick with the Tensei AV that I keep using with my SZ since I keep coming back to it. I will state that the Motore X F3 is not bad, but I haven't put it through the enough paces yet.
I'm testing the Tense from last year and the MotoreX F3 from this year, I can't tell a difference at all in flight or distance. When I use my low launching shaft which is a Matix black, it's definitely lower. I'm not using a launch monitor, only eyeing it while playing.
