Summary: Srixon seems to have made a 2010 model. They claim that this one is for slower swingspeeds and goes straight. I must say, it does the job wel! It flies very straight with a mid- to high trajectory. And goes very far, about 10 meters further than any other ball ive played. It is very durable aswell: played a round without even a scratch on it. Downside is that it does not hold a hard green. So you have to aim on the fringe and let it rol up to the pin.
