I took my Jetspeed 10.5 out today in my lunch break and hit a few balls.
I hit a few and found at 10.5* they went pretty high so I lowered it down to the "Lower" notch which i assume is 9* (3 notches down) and hit the ball about the same height. I did hit a few a bit high on the face but they seemed to go a bit further than my usual 9.5* driver. Playing with very bad range balls was a bit of a let down.
The ball flies hard from the face (no homo) and the feel is nice when u connect one out of the centre.
Cant wait to try it out with some V1's to test it out properly. The sound is a bit different as I am used to the tinny "ping" noise my current driver makes.
