Update: So I've had a trackman analysis. What a beasty-computer! It seems I put a huge amount of spin on my balls. With my 7-iron I was able to hit 9.700 rpm of backspin on it, the pro said this was extraordinay. However, this may be great for approach shots to the green as the ball will drop dead or even spin back, but it comes at a cost (I lost about 12 yards and roll is impossible with 10.000rpm).
It also seams I hit 'normal' distances, but I should be able to get better distances with some adjustments to my swing. My 7-iron (with nex clubs) went about 120-125m carry, 126-135m roll. Would be happy to push it to 140m roll but I'm quite happy with how it goes now. Still tend to hit a bit out-in, making my balls go a bit left, sometimes with a small fade, but working on that too.
I took the advantage of the analysis to order new clubs: Ping i25. Can't wait to have them!
