I've played with the ball and it's not that bad. It plays like normal. I mean, due to the rules there is only a 2oz window for ball weight anyway.
It must be the altitude then, because the amount of overhit crosses and passes is just obscene. I'm sounding like a broken record here but it's genuinely annoying me.
Possibly, you can kick the ball further at altitude. Tis why the goalkicker for the Springboks is so deadly in SA.
