K7JBQ: you can't put a smile on 'em, either. No balata balls in the pro shop
Ah yes, the old smile reminding you of how crappy you just hit the ball. LOL
Those balls were fascinating. If you peeled the cut cover off you had a tightly wound ball of tiny rubber bands. If you cut one of those bands and watched, the ball acted like it had a life of its own as it slowly unwound, jumping all over as it did. Almost creepy. :-D
