The small ball was better in the wind..mass per unit volume and all that.
It also apperaed to sit down in the rough more than the big ball, I guess for the same reason, but the wind was the big difference when I changed over.
I played some of my early Junior golf playing tha small ball and remember the change over very well.
It was at the time the Penfold Ace was still a great ball and I played the big ball Penfold for a number of years before taht company went belly up.
At that time changed to Dunlop, maintaining my British loyalty and didnt move from them until Nike started making golf balls, at about the same time that Dunlop quit producing a high end competitive ball to play with.
